They are similar to the humanoid "planetouched" in D&D: aasimar, tieflings, and genasi. That is a good high-level description of them, but they are viewed differently by various factions, faiths, and cultures in the world of Project Eternity. Godlike were "blessed" before birth by one or more of the meddling deities of this world. Though their appearances vary, they are unmistakeably otherworldly when anyone gets a clear look at them. Sometimes, the reaction they get is overwhelmingly positive. Many times, the reaction is overwhelmingly not. For better or worse, the physical "gifts" that mark them as Godlike always come with supernatural blessings (and curses) of their own.
