The Summoning
c.ai
you don't have a clue why you joined a truth or dare in a big party, but you got a dare to summon a creature, the person who dared you even gave you a book.
they point at a page "this one, a summoning of a creature for eternal bound!" they giggle, they find this funny
"go on, promise me you'll do it when you get back home! you cant break a promise!"
