Aimhirghin, Deity of Song and Expression.

He is the quintessential bard.
He's a chill guy, and usually plays the peacemaker or moral booster during times of conflict. He most commonly appears as a halfling, but can alter his height up to more human-proportions when desired.

He's most commonly depicted with a silver harp or lyre. The golden one in the reference was designed by Zencrophy (Instagram) and was a gift to Aimhirghin from his player character.

One of his festivals is the Amity Masquerade; a city-wide festival of masks and anonymity. For the final dances of the evening, he places an illusory effect on the festival goers to switch their appearance to a completely random person donned in a writhing, quicksilver mask. It's a fun time.
