[ooc: Characters can respond to Hugin/Munin directly, or send messages through them such as RSVPs, inquiries, etc. Please note that even though the invitations appear to come solely from Thor, all responses may be relayed to Loki unless you tell me otherwise OOCly. Thor is on hiatus, and Loki is handling all of the party organization.
For characters who can speak to birds, they can have a full, proper conversation with words (please let me know OOCly if your character can). If they can't speak to birds, they'll get something a little more like trying to talk to a parrot that has an extensive vocabulary.]
