As ap jumps through the portal, he hears a loud, piercing shriek boring through his brains- until it is suddenly cut short as he falls through the air of the new dimension. He realizes he has had awful headaches since he had refused to take the orb, headaches which are now completely gone; but only now does he notice it.
Then he crash-lands into the desert sand, down from the portal which is floating ten meters above in the air.
(Also, a short notice to avoid future misunderstandings: a crag is a kind of high rock
peak, not a ravine. I noticed you got it wrong before)
Meanwhile, on the other side of the portal, Doom and Chryos are assaulted by almost thawed tree branches
(*) trying to crush them, and the surviving dimension leeches coming back for another charge.
(*For the sake of clarity: the forest section is still frozen, but as mentioned before the big tree is less affected, especially this far into its crown. Not that it really matter anymore...)
