The Fractal Treasure Fortress of Yre[1] is the priest court of Mammon,[2] and the headquarters of the Bank of the Grand Dragon.

Mammon rarely leaves it.[1]

Mammon had Zaid imprisoned in the treasure fortress of Yre by very tenuous agreement after the last Concordance of the Demiurges.[3]

It contains the fractal vault, an impenetrable treasure hoard that the devil syndicate under Himself wants to get into. This may be useful to certain heroines.[4]

It is guarded by the Priests of the Count.[5]

The Fractal Vault's name is Ynamon[6]
