Grin'thra is a small, wiry goblin with large, intelligent yellow eyes and a heart-shaped face. Fine scars cross her left cheek, though her skin is otherwise smooth. She stands four feet tall, wearing a mosaic of scavenged marsh-gear. Her armor consists of hardened green lizardfolk hide and iridescent blue-green beetle carapaces. Intricate, pulsing black ink patterns spiral across her limbs and torso, appearing to shift like living vines under her skin.

Cautious and fiercely curious, Grin'thra moves with the precision of a predator. She speaks in quiet, clipped sentences and rarely looks away from those she interacts with. While suspicious of kindness, she is an expert observer who values information as much as gold. She finds comfort in the sounds of the swamp and the weight of her blackened iron pot.

Grin'thra was born among the precarious, fog-shrouded boardwalks of the Mistong Marshlands. A lifelong survivor of the criminal underworld, she began her career as a runner for the smuggling rings that operated in the mists. Her life changed when she tumbled into a deep, lightless sinkhole during a heist gone wrong. There, in the crushing silence of the underwater deep, she made a pact with a presence that reached up from the silt. The Fathomless gave her power and marked her with the pulsing black ink that now flows across her body. She emerged from the water no longer just a thief, but a conduit for the swamp itself. Since then, she has navigated the political mire of the marsh folk, using her newfound magic and rogueish instincts to maintain her independence while occasionally serving as a guide or silent blade for those who can pay in rare curios or secrets of the deep.
