The Sholân Kha was a martial art close to a dance which was developed by the Sylphes.
Each Sylphe clan on Sylvia IV manufactured their own Chameleon suit especially for the Sholân Kha.
Layahna practiced it at a master level.
Behind the scenes
Sholân Kha was mentioned by Franck Vidal for an ambiguously Legends canon roleplaying scenario which appeared in the French magazine Avalon 2.
