REFUGEVILLE

I don't believe using the meat is a very good idea... considering the poison in it, and that the meat is both unknown and probably twisted by Signet magic, it's probably not good for any sort of consumption. It's better to just bury it out of bounds, probably.

The shrunken head should probably be kept somewhere, like the top of the building.

As for Rimewulf's boon, I find it hard to decide between Heaven's Rain, Call of the Wild, and Iron Mine. But I would like to offer reasons for why the other two might be useful.

Sprite of Words is also good, especially considering our newest refugee and that since we are still looking for Signet's boxes, it would stand to reason that we might find people, both allies and enemies who would speak in different tongues. But admittedly, it's going to be a while before we can make full use of it. Still, if it can teach all languages, why can't it also teach the written word... or even the language of life? (Mmm... nah, probably not. Still a good exercise to think about)

The Sacred Entourage is also somewhat useful, but we already have enough hands (and paws) to help with the work. So it's not as pressing an importance. (Though if they can shift to human/half-human form, perhaps then I might reconsider.)

But back to the other three. Everyone's already pointed out they're great. Call of the Wild and Heaven's Rain basically means the village won't starve, and that's not counting other uses such as being able to grow stuff like rattan or cotton to create ropes and fabrics (but the best being for growing trees for lumber), or silkworms and sheep to create silk and wool. While Iron Mine means that it would be easier for the village to develop better defenses and implements to push the village bounds further. (Heck, maybe even create specialized weaponry to be used in wolf form)

Still... right now, the best one I can consider is Call of the Wild right now, if only for the fact that one can probably use much of the animal for many things (leather, food, simple weapons, musical instruments... lots) in the least amount of time. Heaven's Rain would be perfect if we could gain access to the Plant Box ASAP though, and Iron Mine won't solve the food problem considering the ever-growing population.

Either way, if the Villagers choose Heaven's Rain, then they should have a Tapioca sapling mature and then harvest the seeds for planting. If the villagers choose Call of the Wild, then the villagers should summon sheep. They should at least summon around six of these sheep, one ram and five ewes, and have them sheared for wool to both use and sell to the merchants.

...Actually, it might be a bit reaching, but would it be possible to use one of the branches to make a tree? If the branch is cut in a certain way, maybe it can still grow into one, so long as the branch isn't dead. If not, perhaps there might be some seeds or flowers on the branches? It might work, right? That way, there's a chance for us to grow trees for lumber! (And if it is possible then definitely go for Heaven's Rain)
