Thomas is Iscara’s best friend. Iscara sacrificed everything to resurrect him at the Atrium of Forms, submitting to Ten Thousand Guns to heal him. It is likely that her family was dealt with in response to her actions.

Having spent too long across the threshold of death, he has a knack for conjuration.
