Venrich was a soldier for Nidal nation, put on border patrol to seek out Desna rebels in the region, and specifically to inspect merchants coming into Nidal from Molthune. Adhering more to the tenants of Law, than pain and other concepts Zon_Kuthon is famous for, Venrich was perfect for the task. A competent faithful man, but not a complete Zealot. Growing up in the temple he studied anatomy and nobility, as is typical for an aspiring Umbral Agent.
On one particular day, not so long in the past, a Desna worshiper and her allies fooled their way past Venrich's patrol. The agitators were never personally inspected by Venrich, but rather his superior officer, whom blamed Venrich any way. The Umbral Court does not take kindly to failure, and knowing the torture that was in store for him he fled to Molthune having spent so much time on that border he knew it well and had a few contacts in the nation. Still worried he may be discovered he sees this opportunity to be a full fledge Molthune citizen his ticket to a new life and whole heartedly agrees to the terms.
