Ardwen is a Bosmer pilgrim to the Gildergreen that can be randomly encountered after The Blessings of Nature is complete, if you restored the Gildergreen. She mentions she is going to see the tree. She does not appear if you completed the quest by bringing a sapling back.
She is a respectable elemental mage and travels with a dog. Her outfit consists of blue mage robes and a pair of boots.
