Whatever happened to Fitzmilliyun Sparkledrim’s Castle of Illusion? Is it still there in Fell Pass? And is it in ruins or has it aged well due to the wizard’s magics? One wing has fallen into ruin, but the rest of the Castle of Illusion is still there, and functioning all too well (as victims of its traps, wards, puzzles, glamers, and illusions are sadly too dead to attest to).#Realmslore
