Halvor Omdahl

Background

Halvor Omdahl is a powerful adjurator who accompanied Jacoby Franks and Juanita Socorro in their raid against the last jorogumo nest. Halvor studied serecumesh, the form of jorogumo magic. He was the Bastion's expert on the subject, which made him the perfect companion for Jacoby, a rixator, and Juanita, a monachi, when then located and attacked the nest.

It is possible Halvor is the only person still alive who knows serecumesh.

Fall From Grace

After the attack on the jorogumo nest, Halvor had a breakdown where he used his magic to kill four members of the Bastion. Because of his knowledge, the Clostator at the time did not want him executed, so he was sentenced to life in the Gaol.
