It doesn’t make a lick of since bruh. Like why would a corpse be turned into tea, and why would a disciple of the whiteness’s body that was turned into tea instantly cure a coma? Wouldn’t drinking the ichor of a dark gods long dead, rotting corpse straight up kill a dude, let alone an old -blam!- grandpa with 0 immune system strength? It can’t be because he is a guardian because he shouldn’t be a light bearer anymore since his ghost is dead. Even if he was wouldn’t it kill him even harder since it’s pure evil nightmare darkness juice being digested by a being of the light?
