I always envisioned Liches as condescending, oozing with contempt for the living and overly vain. That said, I was never a fan of the “I’m a skeleton/zombie in robes” Liches of the old D&D days. These things have more respect for themselves and are far to concerned with their perceived importance in the world to let their faces reflect their inner corruption. Hence, the death-masks…A sad attempt for these horrible undead to hold on to some semblance of their humanity.
I’m planning on revisiting the humanoid mask idea in the current Lovecraft monster idea I’m working on. The beast’s followers, in a desperate attempt to understand and connect with the thing, forged masks, jewelry and other items for their perverse god..Sort of a reversal of the traditional “god creating in his image” story.
