A dragon whose fetid remains have boiled beneath the deserts of Sudd Tohst since time immemorial. Shingorion was among the many dragons to perish during the war between Mindoriel and Tharador. His own corpse fell into the ashen sands that would one day become Sudd Tohst, where until now, they have dwelt undisturbed. With Ridan’s rise from the sands, Shingorion has emerged with him, enthralled by the will of the ancient Colossal King, whose own will is bound by Myrothlir.
