Stryker will be working with his new Circle, using his skills (Arcana, Enchanting, Medicine, First Aid, Assensing) to help them and make their bond into something more than just group members. He'll also try to pick up any hints and advice that could help him improve his own bond with the Manastreams (I'm hoarding Karma to raise Magic to 5 - it'll take ~2 more runs, but I need to improve Stryker's Magic to reflect his advancement), and server as a Guardian and assistant during any astral travels his group would have. He needs to fit in, and find his place there...
Besides that, he'll ask Brick (reluctantly) to ask Anita if there are any people interested in a more direct 'magical services', like a Combat Sense, Improved Invisibility or Increase Reflexes spell for the run. This could earn him a few nuyen, since he wouldn't have to be on the spot to sustain them, and the team caster - if they have one - would be less strained by sustaining spells.
As for the nuyen, I'll put that new version of the lifestyle together today (I hope). I have an errand to run, and a visit to pay at my old high school...
