Red was chosen as a very young child to one day replace the tribe's Shaman. At the age of 12, instead of taking the usual test for spikes, a young Shaman goes on a vision quest to gain wisdom. When it is time for the Shaman to pass on her spikes, her heir returns and takes them up.
With humans encroaching, it was decided that rather than seek wisdom in the solitude of the barren wastes, he would seek it instead deep in the heart of human lands. His mission is to learn all there is to know of human culture and politics, so he can advice the next generation's chief and keep the tribe and their lands safe without resorting to war with the humans.
He is a curious outcast amid the koloss-blooded population of Elendel; they are all either those who have failed the test, or those who chose not to take spikes and rejected the path of the Koloss. He is viewed with a frustrating cocktail of emotions, frustration, envy, anger, respect, hope, regret. For his part, his feelings towards those who have been rejected is pity and a touch of disdain, and to those who rejected the tribe is a touch of hostility, yet respect for being true to themselves. He makes it a point of trying to be polite and stay on good terms, but there is always a wall there.
In Elendel, the life of a criminal suits him. The high risk, high reward occupation provides him with the funds to get by for rare work, leaving him free for the study that is his mission. As a koloss-blood tineye, he is much sought after, as both look-out and muscle in one. He views human laws as nice starting points, but respects those who have the strength to forge their own path. He does tend to look down on the ones who prey on the weak and innocent, though the "tough love" atmosphere and clashes with other gangs or occasionally conners feels right and natural to him.
His skin is predominantly gray and dark blue; unusually in a koloss-blood, the marbling of his skin has a tendency to look like overlapping waves, or the flowing rivers of mist.
At one point, he justified taking a break from normal humans to study the terris specifically because of their revered status with the koloss tribes, and actually spent some time learning the trade of being a classic steward. What better way to study the rulers of the humans than by standing, unnoticed, at their right shoulder?
