Thoma Erim was a cleric in the employ of the Temple of the Traveller. A Londolond local, she was born into poverty and joined a cleric order as a way to help others. She was responsible for rehabilitating most of the recently Travelled characters that struggled to adjust to life in Xibalba, including Neither Nor six years ago. When not maintaining the Temple of the Traveller, she sought charitable work such as feeding the poor or healing the sick in Londolond.
Thoma preferred not to fight, but can hold her own if need be. She specialized in healing and defensive radiant magic, and was also a skilled therapist.
