Casian Tree

Casian Tree is one of the landmarks in north part of Argonea. It's huge tree that Argons are trying to assimilate.

There is an escort quest where you have to escort Berrul from Northern Teleport Platform to Casian Tree. Further quests unlock after that.

Finishing quests unlocked special property of Casian Tree. Using Iteris Shard near tree raised your maximum stamina by 5, up to 135 for 30 minutes. However unlocking this was removed from quests as stamina system was removed.
