Sula's brilliant orange-and-crimson neck frills flare like a tide-pool crab's fans, their fine ridges beaded with river mist. Her dark olive scales have a pebbled texture across the shoulders and smooth, slick gloss along her muzzle. She moves with a forward-tilted hunter's balance, toes testing each branch before her weight follows; when she launches from a canopy limb, the membranes beneath her forearms open with a dry whisper. Her jaw is broad, and when she laughs her blunt, tightly packed teeth show around a chipped shell bead she keeps wedged between two back teeth. She wears her field coat too large through the shoulders, repeatedly patched with sailcloth, but keeps one tiny brass tide whistle polished bright enough to catch the sun.

Sula is observant and patient with frightened people, yet becomes brisk when someone treats the delta as empty land. She trusts what can be measured but knows that a map can lie after one night of rain. In calm company she is dryly funny and unexpectedly generous; under pressure she grows procedural, counting exits and assigning tasks before she admits she is worried.

Sula grew up in a stilt settlement at the edge of the Whispering Delta, where her family ferried harvesters through channels that changed after every hard rain. She first joined the Shoreline Wardens as a runner, proud of her speed and certain every dispute had a clean boundary. During the Lean Season, she helped mark a migration corridor for a herd of marsh grazers. A survey line she trusted cut across a newly shifted channel, trapping the animals between hungry communities and a flooded bank. Sula broke the marker stakes and led both sides through the night by scent, current, and the animals' calls. The corridor was shared, but one fisher died in the crossing; Sula still keeps his tide whistle. She has since become a front-line patrol ranger, tracking poachers and invasive predators while arguing that stewardship must account for people as well as habitats. Her older cousin Varko, a raft-market pilot, thinks her rules will eventually cost the settlement its livelihood. Their affection survives in practical favors and frequent, unresolved arguments.
