Central Command division 1, highest stat is Justice. Mortimer is a man of few words. Quiet, bookish and somber, Mortimer would often rather be comfortably huddled in a deployment bay chair, writing poetry or with his nose in a book, than working with abnormalities. That said, the work he's ordered to do often gets done with considerable efficiency and a surprising lack of agitation from the abnormality. He may not enjoy his work all that much, but that doesn't mean he's not good at it. A bit of a dour and sometimes depressing man, Mortimer seems to dwell quite a lot on mortality and, particularly, the loss of clerks during ordeals or abnormality breaches. He often leaves flowers at the desks of clerks that have since passed.

Mortimer is somewhat physically frail and not very well-equipped for battling with abnormalities, but has a profoundly sharp sense of justice and abhors violence without reason. It was for this reason that he was chosen to work with Funeral of the Dead Butterflies, and he seems to be quite attached to the abnormality- feeling the same sympathy for those who lose their lives within the facility's walls, and wanting more than anything for the unfortunate dead to find peace in the afterlife. Wearing a stark black suit, wielding a pair of pistols- one black, one white- and carrying a decently-sized, albeit empty, coffin upon his back, Mortimer's attachment to the abnormality is quite visible just looking at him.

Mortimer becomes visibly angry when he encounters an employee who has begun attacking others in panic. While he sympathizes with them having a breakdown and understands that they're not entirely in the right frame of mind, he struggles to hide the cold fury he feels when seeing one inflict violence and suffering upon their allies without reason. Conversely, when he himself panics, he's most likely to grow dangerously self-destructive.

Mortimer likes to vent his feelings and current thoughts in the form of gothic poetry, exploring themes of death, grief and occasionally horror. He thinks it's a bit embarrassing (and, of course, deeply personal), so he only shares it with close friends of his. Those who he's shared said poetry with say it's exceptionally good, if quite a downer to read.
