While Nyan Tamya dreamed of the possibility of a place for him to lay down his swords following his adventuring years, he had a thought regarding how to make the populace safe from attack. Basically, where would they shelter if they fell under some kind of attack, and could not immediately repulse it? After only a short while, he came to realize that an underground portion to the city would be desirable, for that purpose. Meanwhile, it was suggested, it could serve as an addition to the city, an underground portion that would have it's own commerce, it's own industry, it's own residency - but would have more than ample room for refugees would there come time for a need. Nyan agreed with his advisor's idea, and thus, the seed was planted for the bizarre "City within a city" that has come to be the Underground City of Wa-Daisho, within the City of Wa-Daisho.

      Construction on the Underground City did not begin until 109PA. It was clear that Nobunaga Palace, and the Pacific wall were the priority projects in the construction of the new city. Meanwhile the plans for this underground city simmered on a back burner for a time, while Nobunaga Palace was completed. At first, it was simply going to be one large level, under the city that basically was a city under a city, but the concept evolved over time. The first of these evolutions, was that instead of building one large level, numerous smaller levels decending in depth with each one, would be better. It would cause less stress on the above ground structures, and would not be as dangerous in the event of an earthquake. Then it would be several levels which were essentially large caverns containing houses, businesses, and industries built into them. The next evolution however was the decision that the entire place would be constructed not as a large cavern, but instead apartment complexes would be built into the structure, from floor to ceiling, utilizing the supports to the cavern as main supports for the building itself, and thereby adding strength to both the complexes, and to the "cavern" as a whole. Businesses, and industry would also be built in this fashion. Thus instead of a normal above ground city found underground, it would be an underground city, with businesses and homes seemingly built right into the walls. By this point in it's development it was already September of 109PA, and yet construction had not yet been completed. Transportation between levels was proving to be a problem. Some designers wanted large elevators every so many hundred feet, to be the primary source of travel. Others, wanted to place a monorail type system that traveled in a spiral pattern around the underground city. Nyan personally simply wanted it to have small walking ramps between levels. Eventually however, it was settled that although there would be no houses, or separate standing structures in this underground city, there would be ramp road ways to connect the levels. It wasn't ideal, or the most efficient, space or financially wise, but none the less, it was an acceptable method. The only catch however was that NO combustion vehicles would be permitted underground. That was an acceptable catch, and thus in April of 110PA, construction began.

      Once Nyan finally gave the go ahead for construction to begin on the underground city, the decision had to be made as to WHERE they should build it. After a short period of deliberation and hesitance, the decision was made to build it directly under Nobunaga Palace. The first level was planned to be a large scale barracks & military storage depot in any case, so connecting it with Nobunaga Palace as a last line of defense, seemed reasonable. There would be also one other entrance, the main entrance, that was planned to be East of Nobunaga Palace. That entrance put it very close to the Market Square, which would be good for commerce. The construction process was somewhat difficult. Building a structure on top of another structure, underground or otherwise is relatively simple. It's only a matter of reinforcement of the original frame, to sustain the extra weight, and you have to determine the dynamics of the structure as to whether or not it can even stand upright with the added weight changing the structures center of gravity. With building a structure under another structure it's all a matter of balance, reinforcing one area without weakening it in another so much as to cause a cave in that could destroy the structure above and the one below! Entire city walls in history have been undermined in this way, massive walls that were invincible to enemy bombardment destroyed by a tunnel created under them! In this case, they wanted to put a gargantuan cavern under a great fortress - a delicate task to say the least. For the job they hired Garumf Roughcut, a dwarven architect who was very experienced with tunneling on the Palladium World. He assaulted the problem, by going to the far bottom of the planned city, to build the final level FIRST, before the levels above. His reasons? Simple. The deeper one goes, the less the rock displacement will effect surface structures. He explained it in terms of sand. When you build a sand castle, and you make an archway too thin ... what happens? The weight of gravity above, breaks it, and sends it crashing in. Make that same archway thicker however, and it will hold. Essentially the same principle - but then he planned to gradually shave at the bottom lip of that arch way, adding support as he went. Once he drew out his plans, construction began almost immediately. Within three years, all five levels were built, far ahead of the planned construction rate, by anyone's estimates, everyone except Roughcut's!

      Since it's construction, it has grown to be a city in it's own right. A full fifth of the City of Wa-Daisho's population resides within it's confines, which if counted as a separate city, would make it the third largest city in the Republic. There are two commercial levels, a strictly military level, an industrial level, and the largest level - a residential level. They will be described below, with an option of three methods of view.

      Intended as an underground military base in times of war, the Army Rendezvous level serves as an emergency shelter for refugees during peace time, or as a bomb/storm shelter for above ground city dwellers. During times of war, it would have a standard contingent of troops, with facilities to house up to 5,760. An additional 4,120 civilians or troops can also be crammed into the corridors between the "buildings", but this restricts vehicular movement on the level. There are two entrances to the level, the first being a stairway and elevator leading up to Nobunaga Palace. The second is a ramp that leads down to level two. During times of peace, only 16 troops are kept on this level for security purposes. (This number includes at least one Kamiyoroi Cyborg, one psychic sensitive, and at least one mid level Ley Line Walker.) At all times four of these individuals remain at the guard posts flanking the ramp.

      This was the primary commercial district of the Underground City, as intended originally by Garumpf Roughcut - the architect of the Underground City. At the time, it was thought that there would be ample need for this level to supply both the civilian populace of Level 3 and the thousands of troops stationed on Level 1. When Level One's purpose was suddenly changed from permanent military base to a rendezvous and supply point, that all went out the window. A large percentage of the business anticipated on this level was just not going to materialize. Unfortunately for the business owners of Level 2 - contracts had already been signed, and there was no turning back. This has come to be a nasty debate topic during State of the Republic Picnics for years since the opening of the Underground City. It has even resulted in a couple of votes to oust members of the Republican Council, but unfortunately for the Level 2 business owners, more civilians like the idea of their men being at home - than being stationed at a base under the city. The following businesses are found on Level 2;

      Level 3 is the largest of the five levels, having the same sized central portion as level 2, BUT also having an equally large branch to the North and South, and one much larger portion to the West! The western most portion also leads to the Ramp Road, which is the ramp that leads to the main entrance and exit of the Underground City. As it's name suggests it is the home to the multitudes that reside in the Underground City - even still, it is not 100% full, a lot of people have an aversion to living underground and prefer to live above ground, regardless of how cramped, old, or expensive the prices may be. All told, nearly 11,000 people live on this level, but it could easily accomodate 4-9 thousand more, not counting the refugee/troop capacity of Level 1. (Note that following the fall of Tolkeen, MANY families and individuals on this level opened their homes to homeless Tolkeenites looking for a place to stay to get their feet back on the ground.) There are a handful of facilities of interest on this level, they are;

      The second commercial district underground, is the 4th level. Unlike the 2nd level, 4th level gets ALL the business they could possibly want, both from the Residental level, AND from the industrial level on the 5th level!! Every day workers from the 5th level come up to level 4, shop, eat, drink, and play either on their way home from work, or on their breaks. This boom town success of 4th level has caused a significant advertising war between facilities on the 2nd level and the 4th level, on radio and television in Wa-Daisho. Here are the businesses and facilities on this level;

      Completed in 112PA, this plant moved numerous vital military supply productions from the small plant outside of the city to an underground facility completely immune to aerial assault. In its enclosure it employs 3,000-5,500 at any one time. Since its initial construction, it has seen several new projects come across its production lines. In 116PA it began producing components for the first aircraft to be produced in Wa-Daisho, the Type 16 Utility Aircraft. In 117PA it became the key factory for producing major components for the Type 17 Masakari, which it is presently producing parts for clear into February of 118PA.

      Here is a list of major products produced in this plant; Type 7 VSPLR, Type 9 HLP, Energy Clips, 200 mm cannon shells, 40 mm cannon shells, 30 mm cannon shells, 20 mm cannon shells, mini-missiles, Type 6 GPMEBA, Type 13 RFFC, Type 13/15 RFFC, and various components and supplies vital to military service.
