The door takes some work to pry loose. The goblins did a good job of boarding it over, and it is pretty clear that they were absolutely petrified of what lies within. No wonder, given that it appears to have smashed the skull of two goblins in.
Inside stands a once mighty warhorse. It looks wild, its eye lolling in fear and the craziness of hunger and thirst. Under its feet, little more than a smeared mess, lies a third dead goblin. The creature has clearly been starved here for a few days, and looks to be in desperate need of aid.
He stands tall, dark grey, a snubbed nose, but with an incredibly regal standing even in his emaciated state.
He snorts and starts to stamp the ground in fear of you, but also in his lust to be free of his prison. He bolts out, moving past you, and starts to move around the yard, slipping once, then twice, on his unsteady legs. He tries to kick out as you all move together, away from the wild beast. His panic is clear. He snorts again, kicks at a wall of the pallisade, falls onto his hind as his legs buckle, and then tries to stand again. The energy is gone, and he half sits, half stands, staring at you all in half madness.
OOC: Any attempt to calm or similar may be useful, or you can elect to leave the horse, or put it out of its discomfort. Your choice. None of you have handle animal, but Jokad has wild empathy.
