An Endless Night

This story is based off the YouTube red show called: Escape the Night. No I obviously do not own the show but I thought it would be fun to have 20 of my friends over to what it seems to be just a regular dinner party in the medieval era (cause time travel is normal apparently). Just until they realize that it's a dinner party TO DIE FOR. They have to collect 17 orbs and do a ritual in order to seal away the evil that is basically the house itself. They're not able to escape the estate because 1) their time traveling car exploded 2) they're surrounded by a forest all around the house and 3) they're in a different era. They have to go through these challenges to get each orb. Two people are voted into a challenge for the orb. The victor of the challenge will get the orb and continue surviving while the loser perishes. There are 21 people in total and there are 17 orbs meaning most of them are going to die.
