E is a tall, blue-skinned tiefling with a frame that suggests hard labor more than agile thievery. His horns are thick and short, curving back only slightly. He typically wears a heavy leather artisan's apron over his light armor, and his hands are perpetually stained with graphite and grease. His eyes are a solid, glowing gold that sharpens when he looks at a mechanism.

He is a man of patient, methodical habits who speaks very little. He treats every obstacle like a mechanical puzzle that needs to be understood before it can be solved. Despite his imposing appearance, he is remarkably gentle with those weaker than him and maintains a quiet, dry humor among friends.

Raised in the Smokestack District as an apprentice locksmith, E spent most of his life perfecting the art of keeping things shut. He was one of the finest craftsmen in his local guild, respected for his ability to craft locks that were virtually impossible to breach without heavy tools. However, when he saw his masters using these same locks to hoard food while the district children went hungry, something in him broke. He realized that a lock is not just a tool of security, but often a tool of oppression. He began to apply his knowledge in reverse, systematically unlocking the storehouses of the greedy to distribute supplies to the needy. He eventually left the guild under a cloud of suspicion, choosing a life on the road where he could apply his talents toward opening the doors that history and greed have slammed shut. He does not view himself as a criminal, but as a locksmith who occasionally works in reverse.
