Ok, here we (finally) have one of my finished SE plugins. This was the first one I started, kind of just a kickstart for me into modding SE, and thus may be kind of clunkily coded, but it works. I've tested it fairly thoroughly, and there is only one bug I can find, which is documented in the read me file included in the zip as I don't know how to fix this problem, not that it is a major bug. All feedback is welcome.
Updating:
There are not going to be any major updates anytime soon, but when I get Kingsport I will add any tome powers from it to the collection. The same goes for when I get Innsmouth. Also, there will be a minor update sometime when I find some more images as the collection so far is quite small.
