Deepwinter 7 stands in front of the dark forest and concentrates on controlling the wind. The leaves in the tree rustle, winds start blowing, and some leaves detach, being carried away by the wind. The black mist swirls around but mostly remains in exactly the same spots... around the trees. The detached leaves are carried away in the wind and disappear in the gloomy darkness.
As you move into the forest it is like walking into the darkest night. The treetops are not visible, and you most definitely need a lightsource to see*. Even then the lightsource seems to be insufficient, barely allowing you to see about 25 feet on average, sometimes less than that when some of the black mist is more dense than elsewhere. The elves can not even penetrate this darkness with their superior eyesight. Even the dwarf, who grew up in mines where there was no light at all, cannot see through the swirling black mist.
You slowly continue on foot. The ranger does not see any tracks. None of you hear any noise. Nothing seems to be indicating any presence of life. After about five minutes of walking** you see a skeleton, most likely from a human adventurer, on the floor. It is wearing ragged splint mail and has a rusting mace in his hands, and a few metal parts of what might have been a large wooden shield once, now lie near his left arm.
Then suddenly you all hear a loud, almost 20 second long breath, which seems to be coming from all around you.
What do you do?
(* I think that Deepwinter 7 is using one of the continual flame torches, as he does not need his hands to perform his skills?)
(** which direction do you intend to go? You entered on the south side of the forest. It is however very hard to judge in which way the north is different from the south in this forest. No mosses adorn the trees, and the fact that all these trees do reasonably well without light defies everyone's knowledge of how trees should work)
