FRIENDS: As an observer who is constantly on the move, Muninn is not possessed of many friends. At the very least, those are the reasons she tends to cite for this lack, but no small amount of blame falls on the fact that she is not a very social creature. Also, she's been away from Midgard for quite some time. It's not an impossible venture, however, and she tends to be more cordial with beings who are intelligent and sensible, though it can be argued that she has a soft spot for complete and total goofballs, given the personality of her mate.
At present, Muninn has very few friends indeed, for she has spent the last few centuries in Asgard instead of traversing the human world. As such, her circle of acquaintances does not extend very far beyond the Norse pantheon and perhaps a few individuals that she knew before Odin withdrew her from Midgard.
ENEMIES: Like friends, enemies are not something Muninn has accrued in great numbers. In fact, they are a thing she actively avoids trying to make, for she is very aware of the fact that she is physically weak and not very capable of defending herself from any sort of attack. That being said, she is not a truly neutral being and definitely has a distaste for creatures of chaos and strife.
ROMANCE: Muninn is a happily mated raven and, though she seldom shows it, deeply loves Huginn. And, unlike her mate, she is not the sort to be flirty and will rebuff any romantic attentions directed at her...presuming she even recognizes them as such. She can be quite oblivious to such matters, after all.
