Sir Olwyn spent most of his life in the great forests of the Forgotten Realms, where he saved the race of treants from destruction at the hands of a powerful wizard. His ranger henchmen perished in that terrible battle, and he has never replaced them. The treants of the forest rewarded the ranger by creating a special long bow for him, and taught him the secrets of making magical arrows.

Sir Olwyn moved north into Damara, where he became involved in the quest to save the village of Bloodstone Pass. A hearty, outdoorsy man, Olwyn is a great favorite with the children of the village, and teaches archery to them. He has commanded
the Huntsmen Skirmishers in battle.
