These are senses as listed in wiktionary for bregdan: to move quickly, pull, shake, swing, throw (wrestling), draw (sword), drag; bend, weave, braid, knit, join together; change color, vary, be transformed; bind, knot; move, be pulled; flash. All pretty much describe Loki. "Bewi(g)lere" (beguiler) also fits, so you'd get kennings like "bregdende bewilere" braiding beguiler.
Sounds good to me.
I feel like talking about those calamities a bit.
It always struck me odd that, despite being a child of loki, sleipnir is simply "the best of horses", no strings attached.
So given his name means 'slipery', I've elected to have him throw his rider at the hour of their greatest need. Once he learned the destiny of bregdende's brood, Woden has the elves craft him a special binds for each of them, a saddle in the case of Sleapor. But when Ésewyrde (fate of the gods) comes, the girth of the saddle will snap, and Woden will fall into felwulf's waiting jaws. Sleapor was the first of the calamities to be bound, and he will be the last to break free.
Felwulf was the second to be bound. Basically the same tale as Fenrir, although with a twist. Rather than a ribbon around his legs, its around his neck as a collar, and Tiw uses him as his hunting dog. thus ursa minor becomes felwulf on his leash, held by the north star (which is associated with tiw).
Hella (or Helle), being older and smarter than sleapor and felwulf, would not be bound so easily. Instead she was lured into a dark cave deep in the earth with the promise of marriage to Ingwe(freyr), and then a magical gate was put over the entrance. The living can pass through it freely, but the dead can only enter. As she's a corpse, she cannot leave. There she gathers the inglorious dead; oathbreakers, murderers, thieves, and the improperly buried. There she uses her magic to twist them into monsters, the orcþyrs, and they shall be her army when Ésewyrde comes. She is fated to slay Ingwe for his lies.
