Some years ago, I hit my GM with the idea that if my Ally Spirit took multiple forms, couldn't some of those forms be non-organic? For example, my character was a very capable swordsman. Normally my Ally would manifest as an elven woman composed entirely of water, but why wouldn't she be able to manifest as a sword so that I could always have one handy? Other runners wondered if they might have an Ally manifest as a giant bird to give them a ride, or a hose or somesuch. We never got an official ruling, but these seemed like good ideas. I tossed the question to FanPro, and they summarily laughed and said a spirit manifesting as a weapon or tool was ludicrous.
Years later, reading Street Legends, Tommy Talon (I think?) has used his Ally in the form of a motorcycle.

I'm gonna say the sword works, now. Not quite the Lightsaber spell my players keep clamoring for, but I think it'll do nicely.
Thoughts?
