Abomination's graveyard

The "abomination's graveyard" was a site with a large quantity of bones of members of the Great Houses mutated into bestial shapes by the Yssgaroth taint. The graveyard was discovered by Grandfather Paradox's original Godfather-lieutenants and used in Faction Paradox armour. The Faction claimed that the graveyard was a relic of an alternate timeline where the Houses lost the first War in Heaven, but this claim was denied by the Houses, and even experts within the Faction speculated there may be more to the story. At any rate, The Book of the War speculated that the Godfather-lieutenants must have passed through the caldera to access the graveyard. (PROSE: The Book of the War)
