[@Cyclone] For Portfolios I'm think about going towards Wisdom and Knowledge for now and maybe Interpretation if it comes to that. For Cluster I think Understanding would work or maybe I'll ditch Knowledge as a Portfolio and turn it into a Cluster instead.

When it comes to the effects of his Sphere maybe I can have the stars provide some guidance to people when they learn how to trace them like we did in the past. As for the stars themselves they're just a backdrop, one that can't ever be reached. And I talked with Strange Rodent about his Maze being visible from the Observatory. I talked with Crispy Octopus too and he seems fine with his garden being visible too, but just the comet form. I need to talk with the other players on the Celestial Spheres to be perfectly sure of it, but I think it's fine for their Spheres to be visible from the Observatory in some way.

As for his personality I'll have him go to Galbar in person a couple of times to experience things for himself and spread his knowledge. I already have plans for him making the first books when humans become sufficiently advanced. Although I really can't promise any interactions in conflicts I think I can handle his character without too much trouble. And I'll of course expand his character as things develop IC.
