Pickler's history before entering the War College is unknown. In the college, she was assigned to Rat Company and ended up becoming the lieutenant of their sapper line. After their graduation, she was put in charge of the Fifteenth Legion's sappers.
Pickler is extremely devoted to her work, and has little interest in anything else, including relationships. She flunked out of an advanced tactics course, disqualifying her from being captain of Rat Company, in Nauk's words because "if it ain't related to engineering she doesn't care about it".
She is highly competent both as an engineer and as a leader of her command, though is is unknown whether she could do well leading a larger force or one including non-sappers.
Pickler has a good but somewhat distant working relationship with most of her colleagues. She also shares the respect and near-awe of Catherine that most of the Fifteenth have.
Nauk and Robber are both romantically interested in her, leading to them showing off around her and feuding with each other most of the time. While she has little interest in either of them, she has admitted that their affections are a pleasant reminder that she is outside of goblin lands and could start a relationship with one of them if she wanted to.
Pickler has a fairly typical appearance for a goblin, at least to Catherine. However, Hakram has noted that she has very pretty teeth, which he speculates might be why Nauk finds her so attractive. Long and sharp teeth are a major part of orc standards of beauty for both genders.
