Hungering

Sorcerers with connections to undeath or decay might draw their innate power from the hunger of the undead or the power of fungi. Those influenced by the undead often hunger for more magical might, empowering themselves with each creature they slay. Those influenced by fungi can use spores to manipulate and enhance their magic. Hungering

Your innate magic comes from a deep, primal source of hunger and craving. Perhaps your line was cursed for its greed by a god of plenty or generosity. Perhaps one of your forebears was marked by the hungering undead.  Sorcerers with this origin have an unyielding appetite for arcana and go to nearly any length to satiate their desire to increase their magical power.
