Tolkiens Arda – Sveriges stora Tolkienforum

I princip fanns det två typer; elddrakar och kölddrakar. Men ytterligare en uppdelning finns; long-worms som t.ex. Scatha Ormen. I Bilbo nämns också på ett ställe war-worms, men om det är drakar i allmänhet, eller en särskild sorts drakar, eller något annat, vet man inte riktigt.

Scatha
A mighty "long-worm" of the Grey Mountains, little is known of Scatha except that he was slain by Fram son of Frumgar (an ancestor of Eorl the Young) in the early days of the Éothéod.
After slaying Scatha, Fram's ownership of his recovered hoard was then disputed by the Dwarves of that region. Fram rebuked this claim, sending them instead Scatha's teeth, with the words, "Jewels such as these you will not match in your treasuries, for they are hard to come by." This led to his death in a feud with the Dwarves, and however the dispute was resolved, Fram's descendants "brought few good tales from the north of that folk" (from The Lord of the Rings). Certainly the Éothéod retained at least some of the hoard, and brought it south with them when they settled in Rohan. The horn that Éowyn gave to Merry Brandybuck after the War of the Ring (many hundred years later) came from it.
