The avka constituted a sizable predatory bird species originating from the world of Durace, found within the Unknown Regions.
Avka offspring developed inside massive, two-meter-high, stone-like eggs. Upon hatching, these eggs exploded, scattering shards. The newly hatched avka were initially sightless and possessed an intense hunger. They located their food by sensing ground vibrations. Fully grown avka exhibited exceptional strength and resilience, wielding lengthy talons capable of inflicting severe damage upon both airspeeders and starships.
