Teshallas is an agender psychopomp usher who embodies ageing. Teshallas' touch—age—robs mortals of memory, passion, and vitality until death comes to claim them, but Teshallas' touch also allows mortals to mature and can bring them new understanding that they failed to grasp in their youth.
When Pharasma saw that mortals were unwilling to let go of life when their time came, she transformed an asp into Teshallas, whose figurative venom (ageing) would eventually cause mortals to welcome death. Because of this, Teshallas is sometimes cursed and regarded as an example of Pharasma's cruel indifference.
Teshallas is the patron of those who refine natural poisons into medicine, who often grow small gardens of poisonous plants to honour their patron. Teshallas is also associated with intelligent reptiles, such as kobolds, lizardfolk, and serpentfolk, whose souls Teshallas manages.
