Dragobr: Yeah, I found orm (or ormr) too, but it indeed seemed more related to snakes, and doesn't sound very draconic, so I didn't consider it.
Well, Draki it is, then. If someone ever says it's wrong, I'll claim poetic license in the name of familiarity!
amok: Old Norse did not really have dragons, as the traditional English, but giant worms. Especially worms that spew acid and have acid for blood. Or the really large kind, like Midgardsormen. The closest you get is probably Nidhogg, which according to Völuspá eats the roots of Yggdrasil.
Dragobr: Nidhogg is called a dragon, and is said to have wings, even while being serpent-ish.
I've never seen J
ormungandr being called a dragon, however.
mm, there is problem there, since Jörmungandr (Midgardsormen) and Nidhogg (with others) are usually been put in the same category. It stems from Norse not really having dragons in the same sense as Asian and later English. Though Draki and Dragon share the same name, it is not really the same thing. Very similar, but not same.
