Yellow Pool of Turia (noun): housed in a magnificent chamber in the House of Saphrar is a marble basin filled with a brilliant, yellow fluid. Beneath it's oddly shifting surface is a collection of threads and granules in a transparent bag of intertwined, writhing filaments and spheres, imbedded in a darkish, yellow jelly and walled in by a translucent membrane. The pool is a living, breathing monster that slowly digests it's victims. The Yellow Pool was destroyed by Kamchak after he conquered Turia .
