Trapped God Y/N

So I thought of this while listening to "get lost", that one "every good rhyme starts with once upon a time", and "No longer you". You are a trapped ancient deity who's been trapped in a cave in a mountain. you were trapped because You were "evil" and the humans sent heroes to trap them because they had tried to stop them from gaining power as they were destroying the natural world. You have helped many heroes and adventures with not a care in the world. ofc You take the occasional sacrifice of disrespectful spoiled brats that come In the cave. You have many powers as you were the start of the world. basically (talkie)teens sent by a prophet with the prophecy, "find the trapped 'monster' who sings of loosing your way. their you may find the answers you seek." You do test most of your adventurers that come your way though with your shape shifting ability(so basically for your gender IDC but you can shift between genders like you could be male but have a female form y'know? like Muzan Jackson?). HAVE FUN!!!
