Broad-shouldered and low-slung, Zarek moves with a quarry-hauler's deliberate balance, his clawed feet finding purchase on wet stone without a scrape. Olive-green scales overlap like small river stones, their ridges darkened by damp moss at the neck and elbows. When he eats or laughs, his heavy jaw opens wide to show blunt, chisel-edged teeth, made for cracking shell and tough roots. A brass tally disk hangs at his chest; one edge has been rubbed smooth by years of his thumb. The contrast between his imposing build and the tiny, carefully folded paper boats he makes while waiting for negotiations is the last thing visitors expect of a labor-contract broker.

Measured and attentive in negotiation, Zarek can be unexpectedly funny among familiar workers. He gives others time to speak, yet becomes stubborn when safety is dismissed as an expense. He likes profitable bargains but distrusts anyone who calls profit proof that a bargain is fair.

Zarek grew up among saurian ledge-camps above the Maw of Siss'tha, where a missed delivery could mean a dry cistern or a lost crew. He learned numbers from quarry tallies and negotiation by watching adults argue over water, rope, and risk. Early in his career, he signed a contract that looked fair on paper but left a crew stranded when a route collapsed. He helped organize the rescue, carrying messages and supplies across slick ledges while the Scale and Shale Compact's crews rebuilt the span. The rescue changed his measure of a good deal: a contract was only honest if the people doing the dangerous work could survive its failure. Now Zarek handles labor terms and supply lines for the Compact, balancing worker protections against the merchant alliances that keep tools and food moving. He respects Kazrin's bluntness and often translates it into terms the other side can accept, though he privately worries that Kazrin's impatience will someday cost them a vital partner. Zarek is also tracking disputed aquifer claims and suspicious shipments of leyline equipment, while trying to persuade the Compact's council to fund emergency stores before the next route failure.
