King's Vale

King's Vale (王のベール Ō no bēru) is a massive underground city located somewhere beneath the country of Seven. It's a massive city capable of housing over 100,000 occupants comfortably, though at the moment the massive city is only occupied by Thirteen Elite Dark Guilds that come together to have over 600 members in total. These Thirteen Dark guilds forming what is more commonly known as Phoenix Rising. Though the Phoenix Rising guild has members in the thousands, only these thirteen are allowed to set foot and live in this underground city, where many suspect King himself resides.

Description
King's Vale is not only the home to Phoenix Rising's strongest members, but it is also rumored to be the home of the Dark Guild Master, King as well. This giant, massive underground city hosts a little over 600 members made up of thirteen different Dark Guilds currently under the rule of Phoenix Rising. The reason for the city or how it came to be is still a mystery and one that has been kept that way for as long as Phoenix Rising has been formed. The only way to enter and exit the city is through magic portals placed in each of the guild buildings for each guild. Though many have tried to find different ways, no one so far has come close to finding other means of doing so.
