"We talked to the man before he was knocked out," Avan tells Faerydae and Arkanoth. "He had a map of his own and when we combined them there was only one place left to go. The rooms he check had..." He stops and leans in to whisper, "... The other children already killed. He was the only one we could save." Avan points to the maimed boy.
After their reaction and continuing to whisper he asks, "Since there are no more living kids, we should rest and let the attack us, right? There's nobody left for them to eat-" Avan winces as though sick "-unless, they start... They eat... Their fallen goblins."
"When they're weakened after an attack we should be able to go together to find and kill their leader. Are you with me?"
Zork continues, "We must find something here but let's not get too far in case they try to attack the room again." Zorks moves up some more but if he finds nothing returns to the room with the injured and sets up camp for the night.
"I have your back" Krusten replies as she looks too keeping her eye out for goblins looking to spring an attack.
In character "I've got something" Arkanoth digs into his bag and pulls out his 50' of rope. He tries to lash it to the horse, tieing it to the saddle and around the horse itself, and then ties it to the anchor on the wall connected to the chain. "I never would have thought of using the horse if I'm being honest" Arkanoth will try to lead the horse to pull against the wall.
Out of Character Oh man I hope I did that right. Use rope check to tie up the horse properly, and handle animal because "It's not my horse".
Out of Character: You could have waited for the Durid to assist, but whatever works.
In Character: Despite the failure of his idea, Avan is convinced it has merit. Perhaps with the horse and everyone's combined strength they could yank out or break the chain. Avan could even summon a wolf to help pull, but for only 1 round. He has a look at the chain to see how many people could hold it and pull at the same time, Potentially using more rope through the links of the chain.
Specific Action: Zork returns to setup camp for the night in the room with the girls. He will first heap up all the goblin bodies in front of the secret entrance and place it in a way like a warning.
