Krix is a copper-scaled kobold with overlapping scales that gleam like old pennies rubbed bright by countless nervous fingers. Their snout is narrow and foxlike, their ears nicked from years of crawling through broken conduit, and their long tail moves constantly, drawing invisible maps in the dust. They walk with a rapid, careful tiptoe, pausing after every third step to listen through the soles of their feet. An oversized leather vest hangs from their shoulders like a collapsed tent, its pockets swollen with screws, corks, wire, chalk, and half-eaten biscuits. Copper wrenches clatter from the vest whenever Krix moves, while three magnifying lenses are strapped over one eye in a crooked brass frame. They wear a battered brown hat that is far too large, causing the brim to dip over their face whenever they become embarrassed. Despite their fidgeting, soot-smudged appearance and obvious love of machinery, Krix has an unexpectedly delicate presence, handling injured creatures with the slow reverence of someone repairing a priceless clock.
