Description
Ab-Tekeli are miserable creatures that are warped by otherworldy curses. If a humanoid studies forbidden knowledge they sometimes are corrupted and turn into Ab-Tekeli. Sometimes the form is given as a curse by an angry eldritch being. Either way, the only thing that fuels the Ab-Tekeli is its hunger for more knowledge, even though their minds are just pools of corrupted sludge at that point.
