You have no helmet, neither on nor with you.
Tired you drop against a nearby rock outcropping and fall asleep...or at least you try to. The Pain you are feeling, the difficulties breathing and a constant level of noise keeps you from resting at all.
Nonetheless you close your eyes and eventually fall into a restless slumber, any rest denied by horrible nightmares.
You awake to a blinding light flittering past your closed eyelids.
When you open them you first realize that you can see again. The next thing you see is a pale light in your vicinity. It is flickering in the air, suspended by nothing, a ghost light?
Looking around you you find yourself still next to the river...thirsty you approach it and nearly sink your hands in it before you realize what is wrong with it: there are blades in it.
Blades are flittering down the river at an immense speed, cutting through it like pikes...the fish not the weapon although actual pikes are drifting with the current too.
[93-25 Piety] Gjöll. The River of Blades...you groan. And immediately buckle over in pain. You are in Helheim or near it in any case. You realize that you are very much screwed. Cursing you try and fail to figure out why you would end up here.
Finally you decide that it is time to leave and there is only one of two places to go.
A. Upriver, to unknown Places
B. Downriver, towards Helheim and Eljudnir, the Hall of the Queen of Death herself, Hel.
