Nagas
Nagas are intelligent serpents that inhabit the ruins of the past, amassing arcane treasures and knowledge.
The first nagas were created as immortal guardians by a humanoid race long lost to history. When this race died out, the nagas deemed themselves the rightful inheritors of their masters’ treasures and magical lore. Industrious and driven, nagas occasionally venture out from their lairs to track down magic items or rare spellbooks.
Nagas never feel the ravages of time or succumb to sickness. Even if it is struck down, a naga’s immortal spirit reforms in a new body in a matter of days, ready to continue its eternal work.
Benevolent Dictators and Brutal Tyrants. A naga rules its domain with absolute authority. Whether it rules with compassion or by terrorizing its subjects, the naga believes itself the master of all other creatures that inhabit its domain.
Rejuvenation. If it dies, the naga returns to life in 1d6 days and regains all its hit points. Only a wish spell can prevent this trait from functioning.
