Background: As he would tell it, the half-orc was cast-out by family at birth. The Temple priests to Oghma in Bard's Gate supposedly took him in and raised him for a while. At some point, he ran away in search of his mother. The she-orc he found horrified him.
He was imprisoned as a slave in her tribe, and still bears the scars of his servitude.
What he learned of Grotaag and the Orc ways terrified him to his core, so he ran away again. Once released, he traveled for most of his short adolescent life. He has led his life as a bard and occasional apprentice.
Personality:
Whereas most bards would enliven or cajole you, Makirut aims to scare you. He has tweaked several Orcish fables, and presents them as horror stories in human taverns on his travels. He believes that through confronting these horrors in a safe setting, the forces of good commoners will be better prepared.
Any traveler who truly gets to know him will find him as lighthearted as many a voyaging bard. His intimidating stage presence is merely an act he uses to get by.
Motivation:What motivates him more than anything is his need to know. What training he has received is piecemeal so far. His bold independent streak has led him through a quick string of mentors: Longhunter rangers, frontier magicians, and rough merchants. Not all of them remember him fondly, but Makirut always means well.
Subjects of ancient and academic interest intrigue him, but he yearns for first-hand delve into Rappan Athuk. As a result, he's willing to take huge risks, not for the prestige, but for the lessons hiding within the earth.
