As what Shazirah has explained about the Inn merely as a location. Raikorsai helps nearly everyone. He's a character whos always on the fence, ready to hop onto any side. It just happened that Tribunal had never asked Raikorsai for help before and if there is, it happened to be a wrong timing. If Imms taken notice, Raikorsai had helped Scions before, but once or twice I think. It isn't part of the role, but anyone who can provide Raikorsai(audience) with a good fight, he'll be more than willing to stack the person up with spells.
