just for starters, I'm a muse of blood,
classpects in general can be complicated and I like when people get others input of their classpect because of the bias that can come from just looking at yourself from your perspective and the type of person you think you are. I personally talked to my moirail (yes I unironically have a moirail) and my other friends who yes aren't fans but I have explained things to and they were happy to help my autistic ass. for a long time I had placed myself in the role of muse of heart, which I do think fits me in a way but blood definitely fits me better. just for a little rundown..
blood: as an aspect can be linked to the bonds and relationships you have including friendship, unity, along with attachment and obligations the holder has to others, as the Extended Zodiac says "Blood-bound are absolutely leaders, but they inhabit more of an inspirational role than a commanding one. They are prophets, rather than generals, giving others the strength and motivation to keep fighting. The Blood-bound can dispense excellent advice even when their own lives and interpersonal relationships are disasters." and "No matter how bad things go, a Blood-bound can always count on friends and allies" and this is very fitting to the cannon blood players and myself I think.
muse: not much is known about muses because of the lack of them in cannon and the fact its a master class but from what me know or from speculation, muse is the most passive / group oriented class, on top of this muses will completely embody their aspect well being an inspiration to others through their aspect. (I may have gotten this a little wrong im writing this in the middle of class)
honestly I don have much else to say,, errrrm
