Dungeon Dilemma - Medusa Curse

 So these kind of small detached encounters or dilemmas are something I've been wanting to see made for a while now after I thought one up and never really shared it other than in a passing conversation on discord.
Now however I had come up with a second one too ad instead of just leaving these bouncing around inside my head I thought I'd write one of them down in an attempt to start a small trend in the blogosphere that I could then harvest the cream of the crop from since surely other people have bunch of interesting ideas to throw into the pile too.

Thus I present to you:

Medusa Curse

A relatively simple prison that can be dropped within a dungeon or temple or shrine or whatever your adventurers likely are going to be delving, constructed with sacrifices of eight individuals to bind a monster/villain/whatever to a place.

Setup:

• 3x3 grid of 15' by 15' rectangular rooms, each linking up to their adjacent ones and each separated by heavy curtains rather than doors.
• Each outer room has a statue of a mage/priest/whoever were the ones to seal the bad thing here.
• These statues each are facing in towards the middle room.
• Statues in corner rooms have a 50/50 chance of looking towards either of the doorways leading in.
• In the middle of the middle room stands a statue of <insert whatever ancient evil was sealed here>, bound up and with a hood or a sack of some kind covering their/it's entire face.

How it works:

The statues are a result of a "medusa curse", an affliction which transfers from one person to another through sight, mimicking the way a medusa's gaze works.
When something roughly the size of or larger than the affliction's current host enters within the host's line of sight the curse will begin transferring to it's new victim, un-cursing it's current host in the process.

• Treat this in the same way you treat regular petrification in your games, except additionally if somebody gets afflicted by it the "statue" they got it from is now un-petrified.
• Yes, this means halflings and dwarves are safe if you decide all the outer "statues" are human sized.

Mixing things up:

Something to consider is how would other denizens of whatever dungeon you drop this into have interacted with it in the past.

Are there perhaps petrified adventurers frozen in weird poses in the first few rooms with the original "statues" missing from those rooms? Did the evil that was sealed here get freed and is now roaming the dungeon, luring it back here and tricking it to get re-petrified being a potential way to deal with it?

What if instead of something immesurably evil being sealed here, it's evil cultists that have sealed an angel or a hero of old in this place?
