Sizhen is unconscious, but seems relatively unharmed. Bryn sits him up in the corner of the adjacent room outside of the filthy bat den. He does what he can to revive him. Sizhen seems to be slowly coming back, but he is extremely groggy, not talking for a while and slowly opening and closing his eyes.
Thorn cuts one bat off of Maeriks and sees that the big Dannein is in bad shape. Thorn drags him outside to the other room, getting Bryn to help. Bryn does his best to tend to Maeriks while Thorn and Kray work together to lift Ivor's body out of the bat den and into the adjacent room.
Everyone moves out of the horrifying bat room, which is a scene of carnage with blood and bat shit everywhere, gruesome remains of cut and crushed bats. The brained corpse of the giant bat still lays near the door where Thorn killed it. They close the door, shutting that scene away, and Bryn uses a tool to click the lock on it.
Maeriks continues to struggle. Everyone else breathes in and out desperately. They are exhausted. Sweaty. Covered in blood and bat filth. Their muscles still twitching from the poison effects. Headaches. Coughing.
...but gradually, they begin to regather themselves.
Sizhen awakens fully and stands up, still facing the remnant poison effects but now full conscious.
Move from 4 levels of Exhaustion up to 3 Levels of Exhaustion after 3 minutes away from exposure.
