I do like the first two ideas you had though. I'm probably going to use those. I think the second one needs a bit of help though. I'm not sure exactly what the mechanic should be to "hunt" the aberrations. I'd like everything in the tree to appear naturally grown or made. So jars are out. Any sort of statue or figurine needs to be grown into its shape rather than carved or something. I'll keep thinking on it, thanks for the help!
