Dragon Gunfire/Nidavellir

The guild hall of Dragon Gunfire, also known as Nidavellir, has been around since the guild's conception.

Appearance
Dragon Gunfire's guild hall is an underground catacomb located underneath Crocus, Fiore. It was excavated and shaped by Dragon Slayer Magic. It appears to be a catacombs of sorts, with the only light in the guild hall being, light emanating lacrima. The guild hall is always under constant repair to completely ensure that it doesn't collapse in on itself. There are various rooms throughout the guild hall, including the job board room, dining hall, and several other recreational locations, including a gym, game room, and pool.

Protection
The guild hall has an enchantment over the entire guild hall, something Aether did using his Jutsu Shiki. This makes it impossible for anyone with malefic intent capable of entering the guild hall. It also acts as a shield in case the guild collapses in on itself, for any natural or unnatural reason, holding until the guild members can escape.

Trivia
Nidavellir is the realm of the dwarves in Norse Mythology.
