Basically, there's no reason not to switch POVs between prots and antas (I find it a little curious, though, that the antagonist only gets so little chap space)

In my case, I'll switch between the POVs of my MMC and my FMC. There's no classical physical antagonist; the antagonist in my case are rather the prots' personal issues and pasts that get in their way and unite them at the same time.

Title-wise, I guess that's totally up to you as well. Your story sounds fantasy. If I'd write a fantasy and were title-conscious, I'd use something like "Aniwaya - Valley of the Wolf Clan". But I'm a realist.

My title, for example, is Bound.

It's partly because both protas find several uncanny connections between them that'll ultimately help them face their issues and partly, because them meeting has some fate element.
