Kaelen cuts a tense, austere figure whose deep blue stone skin has the matte texture of river-worn slate. His movements are economical and deliberate, as if every gesture has been measured against the pressure in a pipe. Sharp amber eyes flick constantly toward drains, ceiling joints, and dripping valves. His short dark hair is flecked with white salt, though he is not old enough for it to be natural. Thin blue mineral lines shimmer beneath his skin when he feels anger or fear, making him look briefly like a cracked aquamarine statue lit from within. He leaves behind the impression of a sealed door that has learned to walk. The unexpected contradiction is his hands, which are broad, scarred, and brutally strong, yet he handles fragile glass gauges with the tenderness of someone touching an injured bird.
