I've made an FAQ because I noticed a lot of y'all struggling heavily with this, so uhm, yeah.

Q: How do I activate the powers?
A: The Alt Activation is H, so if F doesn't work, press H, or try to go into the power menu and enable it if it's disabled.

Q: Who is Charity?
A: Charity is the combination of the Reality Eater and Z'othra.

Q: How do I unlock every secret?
A: If you want to grind each one, check out the pinned forum. Now if you want to be lazy, type Beyond Nowhere Unlocker in the search tab and spawn it, then restart your map.

A: Is this mod safe?
Q: Simply, Yes.

A: Why does my PC crash with this mod on?
Q: You probably just have a lot of mods enabled, try deleting some.

That's all, feel free to ask me any questions and I'll try to add them all to this.
Now I can't do much about the lore, because I don't even know much about that, so I probably won't have a definitive answer on that.
