I've been thinking on Aspects and temporary powers and Sidhe favours, and I now have a question: How would one go about making a PC an esquire to one of the Faerie Courts, like Harry and Morgan post-Proven Guilty?
The easiest way would be to make them one during character creation, but I was wondering how you could do this as a reward. You could say that everyone has to replace one of their Aspects with Esquire to Summer/Winter, but that seems a bit arbitrary. I see two other ways to handle this: either you have a custom power of Esquire to Summer/Winter [-0], allowing you to call in one favour, or you have a fragile temporary aspect (one free tag/declaration) of Esquire to Summer/Winter, which lasts as long as you don't use it.
Thoughts?
