Well, I'll go with three words as part of the name to match the other dragons I know of in Skyrim.
Also, it has been a while since I played Skyrim, so I might end up making a few mistakes.
Anyway, I already kind of have a character for Skyrim, considering that's how I ended up making Izviing.
Name: Iiznahviing.
Gender & Race: Male Dovah.
Role: Pretty much just working to protect his species.
Strengthes & Weaknesses: He's a frost dragon, so he's resistant to frost, but weak to fire.
Personality: Quite aggressive towards humanoid species, but might let them talk first before he decides to kill them. He specifically hates elves more than anything.
Breath Weapon & Shouts: Unrelenting Force, Frost Breath, Become Ethereal. (And if Frost Breath isn't being considered a shout for dragons, then also Marked For Death.)
