Heh, so much lore, too little time. I once referenced the Stone of Jas in one of my stories, in The Gothic Wolves I think. Someone used the Stone of Jas to create a foggy otherworldly realm, consisting of vast pillars, floors, arches and such that shifted; they rumbled to spell out "god" in Morse code.
It eventually led to a dark, transparent, shadowy realm of which the sky was a single immense monster with many dragon heads on the ends of necks, as well as hanging scythe limbs. It housed several glass cubes that could change shape, which could manipulate the shape of the world, as well as open gateways into other dimensions. Undead Temple Knights, who were beaten and then tortured to death, were trapped in the realm; Black Knights were briefly mentioned to be running around, presumably escaping the same fate as their White counterparts.
