What happened to the Soul Spell?

I’m aware that there was an official Soul Spell that was going to be released by Warpfrog, but it was canceled. I remember having a mod made by someone else that was an actual thing, which I played about 5 months ago. I had a mod called the Soul Spell or something similar to that. You could siphon the soul out of your enemies and use it to heal and cast spells, and here was a meter on your wrist showing how much soul you had. Since then, I've reset my PC and lost the mod, and now I can't find it anywhere. I've checked on Nexus and a few modding servers, such as Jenix's Modding Server, Lyneca's Mods, and The Bird Nest, but I still can't find it. Does anyone know about this mod, where it went, or have an old download of it?
