The Dead Dungeon

RJ was a great and powerful dungeon,  a human reincarnated as a dungeon core he was proud of the monstrous humanoids and deadly traps he built.  Unfortunately the awesome loot, and powerful magics that came from him drew the attention of many nations.  During a brutal siege in which the elven nation tried to defend against the Southern dwarven kingdom, a rogue human faction snuck in and shattered RJ's core.  Now the dungeon town is a burned ruin, the magnificent hundred level dungeon has colapsed, and in a tiny lonely crack, a shard of RJ remains.  Lacking access to any of his old monsters or abilities, can he ressurect the dead dungeon? more importantly, can he stop the sentient races from  discovering and fighting over him once again if he does?
