Okay, so I have a question. Sacrifices, are they immediately assigned to someone, or does someone have to claim them as theirs first? And what do they do with the sacrifices if they aren't claimed or given to anyone yet?
This can go multiple ways, actually.
1) A sacrifice with a particularly useful skill is offered, for example, a blacksmith or a tanner. They will nearly always be picked up by a pack since they are worth their weight. If a particular wolf takes a shine to one of those kinds of sacrifices, then they might engage in a claimant relationship. However, regardless, that sacrifice will be kept within the pack and likely treated very well.
2) A sacrifice who has a fairly useful skills, such as weaving or cooking. Again, they would be picked up by a pack that could find use for such skills. For example, a weaver might get picked up by a pack that runs near enough to human settlements to sell such things. Claimant relationships happen here as well, but again the sacrifice's place in the pack is dependent on their skills.
3) A sacrifice who doesn't necessarily have any skills but is exceptionally beautiful. In this case, they'll only get picked up if a wolf wants them and has a high enough position in the pack to support them.
Occasionally sacrifices will be given as gifts between packs, or as an honor gift from a warrior to their alpha. These are fairly rare occurrences, however, since sacrifices are usually treated well, not as property. Does that answer your question?
