Description
This is it. You've passed all the tests of the Hyldsmeet... all but one. You've risen among our sisters' best and fiercest.

The final test is at hand. The Drakkensryd - the true test of a Hyldnir's worth and warrior spirit. It'll be you, your riding drake, a chained harpoon and a score of your sisters vying for dominance.

Show no quarter. None will be expected.

Progress
Begone!

Completion
Sif... is that you?

Trivia
The word "Drakkensryd" seems to have a Germanic etymology (word origin). It is similar to English dragon ride and Dutch drakenrit. That is actually what this quest is about. The purpose is to ride on a dragon and attack mobs as explained above.
