Some of my all time favorite monsters are th eundead, especily liches and skeletons and ghosts. because you can do so much with them. Lich in particular makes for intresting designs. This one is based ont he concept of a "holy lich" and is a high priestess from some ancient civilazation that hade a sun god or goddess. Solar deity dosent have to mean lawfaull good, the sun is harsh,unforgiving, it brings draught and can scorch the land and harvests.
