Profile

A former career criminal and catburglar, now working for The Agency. He has a gland implanted in his brain that allows him to cover himself in quicksilver, rendering himself invisible. The main drawback of the quicksilver gland is the periodic Quicksilver Madness: a flaw engineered by scientist Arnaud DeFöhn causes the gland to leak quicksilver into the brain of the host, leading to a breakdown of higher cortical function, initially leading to a lack of inhibition. The eyes become bloodshot and short bursts of pain result, but the host maintains most control over his behaviour.

However, as the situation progresses, the pain becomes more severe until the host enters the Madness, at which point it seems to cease, but the host begins to exhibit violent behaviour as his darker impulses are released. The whites of the eyes become completely red at this stage.

Darien is a highly talented thief with expert-level breaking and entering skills, learned from his many incarcerations, and finds these skills quite useful in his new career as an espionage agent. His trademark expression is "Oh, crap.", usually said when he realizes he just got himself in trouble.
