Yall I am tired here is a dumb theory I sent to my friend copy pasted from pisscorp
The revive book had to come from somewhere, another point in time past or future, to bring someone back to life they need a body that could easily be made of minerals and they could be some kind of nymph
thats cool on its own but it gets worse
maybe the material theyre made our of shouldnt be so attainable it shouldnt take a skip and a jump should bring someone back to life so maybe youd have to go to the nether
sapnaps got that whole born of fire thing going on so maybe karl met him in the past and when he came back he had something of his and used the revive book to bring his sould back and make his weird lava monster man
they decide the books too op to keep around so they give it to someone who wont need it
Schlatts not sober enough to remember where its from, karl forgets, sapnap keeps quite and it ends up with dream who doesnt know anything about it
its not likely in the slightest but no ones stopping me from vibing with it
