I'm not sure if questions like this have been answered in another topic but reading the character sheet and the intro fiction got me wondering. Muses are, from what I gather, AIs that float around in the character's head (their cortical stack I assume? or something else) and do... stuff, like scanning and sending messages like in Lack, but I'm certain there's more to them than that, which has spawned the following questions in my mind.
1) What exactly are the functions of a Muse from not just a character's perspective, but also the player's persepctive, so... setting and rules abilities and bonuses (or penalties)?
2) Does basically everyone in the EP setting at least have access to the possibility of a Muse, or is it something that's ging to be unique to Firewall PCs?
3) Who exactly is going to be in control of the Muse as far as roleplaying goes, just curious about this one because I think it could provide some very interesting roleplaying oppurtunities if the GM controlled each character's Muse.
