Krackle is a unique kenku with vibrant, electric blue feathers that shimmer like a starling's wing under direct sunlight. Unlike the soot-colored plumage of his kin, his feathers often spark with faint static. He wears indigo robes that are worn at the hems and carries a small pouch filled with blue glass beads. His eyes are a striking, pale silver that seems to reflect distant lightning.

Krackle is a bundle of nervous, frantic energy. He rarely stands still, his head constantly twitching to track every movement in the room. He views magic as a wild beast he is trying to bribe into obedience rather than a skill he has mastered. He is intensely curious about sounds and will often pause in the middle of a dangerous situation to record a particularly interesting scream or explosion with his mimicry.

Krackle hatched during a localized weave collapse in the High Azure Peaks, a rare occurrence that forever stained his plumage blue and infused his blood with raw, unrefined sorcery. While the other kenku of his rookery were content mimicking the sounds of the mountain winds, Krackle found himself mimicking the roar of arcane storms. This internal power was too much for the secluded aerie to handle, especially after a particularly bad sneeze caused a localized gravitational reversal that lasted for three days. To preserve the rookery, Krackle was given a set of traveler's clothes and a crystal focus then sent into the wide world. He has since traveled from the frozen north to the warm south, collecting the sounds of magical disasters. He believes that if he can hear enough spells, he will eventually find the specific frequency needed to stabilize his own soul. He is a wanderer by necessity, always looking for a place where his surges won't cause too much paperwork for the local guard.
