Len'ulen is a spiritual warrior Aviansie that players will find upon inspecting a small urn on Stormguard Citadel. The urn can be found near the Wingsuit v1 (damaged) on the island with the keshik ger excavation spots. Upon inspecting the urn, Kal'armal will appear and wander for approximately 30 seconds, and then play a death animation and disappear. Players may respawn Kal'arma by inspecting the urn once again.
When interacted with, they will only give the name "Cor'son".
Finding Len'ulen along with the other aviansie spirits is required for the Abbinah Resting Here For a While achievement.
