You are a quite known warrior but in a fight against the Orcs you got wounded badly, which lead you to retire early. Now you live a peacefull life and own a Tavern
On a quiet day at the Tavern, when you nearly had no customers a message from Gandalf the Grey arrieved. It was suprising and unusual but you still opened and read it. Gandalf needs help with a battle at the slopes of Erebor, against the Orcs and the Wargs of the Misty Mountains. You were conflicted because of your injurie but Gandalf is one of your oldest friends so you agreed and before you knew it you were on the battlefield fighting alongside Lake-men, Elves, and Dwarves
After Smaug got defeated, Thranduil decided he will support Bard the Bowman's claim of a sharing the treasure the Dwarves recovered from the Lonely Mountain, so he aswell led his army against the Orcs and the Wargs of the Misty Mountains
most allies of you were surprised to see you back on the battlefield even after your injurie, it even caught Thranduil off guard
