I have to get one more post in an RP I'm in, but after that I would love to be your RP buddy? I would probably offer up Aurora (Basically me, oPo) and then her good ol' pal Demetrius. Aurora would probably be in human form, but I'll post her Lucain form as well. And Demetrius will be in his quad form. Aurora is just an overall adventurous person, really in touch with nature, and has a magical control over plant life and the like. She's awfully bubbly and exciting, and doesn't really think things through and instead will just go with her gut decisions. As for Demetrius, he is the most knowledgeable pets we have in the Pen. He's older, actually hundreds of years old, and although not as crazy as Aurora does hold his own.
As for plot ideas, it depends on how much of adventure you would like. I'm good at those. >D! Do you want something just like traveling together, or something really in depth and will last long?
Oh and also, I was thinking perhaps Aeragorn? I noticed you haven't roleplayed him yet and since you would like to develop his character, perhaps you would like to take him?
