Haakoro is a supporting character in The Sanctum of the Sphere. One of the few humans to have a role in the series so far, Haakoro encounters Brazel and Grond while tracking a signal emitted by a device that they have been contracted to steal.
Haakoro is in his early twenties, with olive skin and straight black hair that reaches his shoulders. Little has been stated about his past or background, and he operates on his own, without benefit of affiliation with any organization. While humans typically have a surname, Haakoro either does not have one or is not interested in revealing it.
Haakoro is brash, impatient, and occasionally rather rude, and Brazel and Grond are not terribly fond of him. He is also either exceptionally talented, incredibly lucky, or both, and appears to benefit from coincidence more often than anyone ought to, a fact that has not escaped the other main characters in the series. Whether this represents random chance or some sort of talent on his part is yet to be revealed.
