He's a Citizen of The Universe... Nuff said...
slowly fades away with Chime noises playing him out
from his lore
Bard travels through realms beyond the imagination of mortal beings. Some of Valoran's greatest scholars have spent their lives trying to understand the mysteries he embodies. This enigmatic spirit has been given many names throughout the history of Valoran, but titles such as Cosmic Vagabond and Great Caretaker only capture a fleeting aspect of his true purpose. When the unknowable structure of the universe is threatened, Bard steers all existence away from utter annihilation.

Bard's presence causes magical chimes to appear, which grant Bard experience, mana, and a burst of speed. Additionally, lesser spirits follow Bard and aid in his attacks

The question is what Gender do we want Bard to be http://img08.deviantart.net/7599/i/2015/101/9/f/_lol__sexy_fembard_and_fembraum_commission_by_n1ps-d8pbs5m.png I know my answer [zombie-nunu-hearts]
He doesn't have time for genders. He has Chimes to collect and ancient / powerful relics to keep out of mankind's under developed clutches.
