Ashyen is an ancient tree, residing in the Cenarion Refuge in Zangarmarsh. He is one of two objectives of the quest Blessings of the Ancients which you can get once you're friendly with the Cenarion Expedition.

After you've reached a friendly reputation with the Cenarion Expedition he will give you a buff of increased attack power by 30 lasting for 30 minutes when you ask him. He'll give you the buff regardless of whether you've completed the quest or not.

The other objective of the quest is Ashyen <Ancient of Lore>.
