Sulfurwing

Natural basis: cave swiftlet + echolocation + sulfur caves

Role
ScoutController

Uses click echolocation, builds nests on sheer walls, tolerates air rich in sulfur compounds and finds exits by following air currents.

Origin

Colonies settled in vast volcanic caves, where haze and darkness made ordinary sight unreliable.

Appearance

A dark cave bird with a pale throat, yellow brows, broad yellow edges on its short wings, ochre feet and a short tail.

Sulfurwing — Front

Signature ability

Sulfur Swirl

A cloud on the densest cluster: enemies in a 3×3 area take 100 damage, 35 Toxin damage per second for 4 s and are Blinded for 2.5 s.

Passive trait

Sulfur Navigation

Weak Toxin Fields don’t hinder Sulfurwing’s sight or orientation; on the contrary, their air currents reveal the shape of the cave to it.

Evolution

Line E-21: Bird of the Cave Dusk

Duskjar → Sulfurwing

Condition: nesting permanently deep inside volcanic caves.

Cryptic vision is no longer its main advantage. The species develops click-based echolocation, tolerance to sulfurous air and shorter wings for maneuvering close to the walls.
