So, I'm the D&D of a Forgotten Realms Campaing of my own brew. My group of 5 players and me went through all of Rise of Tiamat. And are now playing 500 years after the failed rise of Tiamat that gave Thay the opportunity to rise in economic power over many lands. Part of it was creating powerful magic items made of undead. Arcane covered patches of fleshy skin stripped off of undead. They are powered by a drug called Synth powder, or in some lands red dust, which is actually ground up Undead. (Leave no part of the undead behind). Highly addictive and provides short term boosts to stats.
The entire party refuses to use synth so, they wanted to find a way to reactivate the arcan patches. The Chaotic neutral Warlock of the party beseeched his Patron whom he's asked for the power of vengeance upon those that killed his sister. His Patron is Orcus, ruler of the land of dead and has a vested interest in stopping the spread of synth powder to stop the production of undead on Faerun.. His land should be the only undead kingdom... Not Faerun... (Unless of course he becomes ruler.. then he'd be o.k with it.)
He sought an answer to finding an alternative source to power these patchworks of arcane runes, so the party could use them without synth powder. Some provided +1 AC, an extra up to level 2 spell slot, and as powerful as activating Regen on the character. I thought some were pretty cool and it opened the door to additional options. For each person could have multiple patches. E.g. they could potentially have 3 patches of a 2nd level spell storing. That's 3 extra magic missiles! In some cases maybe even Over powering.. The downside was that one had to be addicted to synth powder in their current form.. So, they wanted to find a way to use them without using synth powder. The Patron provided them an answer. Said that they would find their answers and provided a Blanket of skin that had an ancient language on it to seek out someone that would have all of their answers.... I gave multiple clues that this may not be the best idea.. e.g. it came from an evil Demon for one.... 2.. It was a blanket made of humanoid flesh... With an ancient writing they needed a powerful necromancer to read for them to open the portal.. ...
They said, sure, let's do it...
Well, they ended up seeking out an Elder Brain and Mind Flayer Colony for their answers.. (What other allies would Orcus have right? ) In exchange for helping them migrate to more civilized areas full of undead, the Brain would provide Elder Ichor as a psionic fuel source for the patchworks of skin. It wouldn't last as long, the patches once sewn into the body would only remain charged the day the ichor was applied, but it enabled them to use the patchworks and recharge them without synth powder. The only cost is assisting them in migrating East to a more civilized area to establish a new small mind flayer colony... Now the party is divided. The two chaotic characters want to do it.. Think it's worth it. Two lawful characters say absolutely not. 1 neutral neutral character is more or less. No. So, it's 3 against two, but now they're all afraid of becoming slaves to Mind Flayers and an Elder Brain. Which, in all reality... They would gladly take them on as slaves to do their bidding without any costs....
So, now, I'm presented with not so good options... Do, I have them all attempt to be mind controlled by the elder brain? Basically. Initiative and battle ensues which would kill them. They're level 5. Mind Flayers (multiples) are all CR 9 or above and an elder Brain I don't remember for sure but think it alone is around CR 15. They would be demolished.
Option 1: An agreement amiable to the Mind Flayer colony is not reached, fighting ensues. (what should probably happen.)
Option 2: An amiable agreement cannot be reached, and I do some finangling, provide each of the characters 2 intelligent saves. Upon two failures, they were now secret servants to the Elder Brain and if they fail both checks, they are unaware of their servitude they just are simply more open to suggestions from the Elder Brain on what to do.. (could be fun to have some of them know they are secret servants and afraid someone would find out, and one or two others have no idea in-game that their characters are being controlled.)
Option 3: Continue allowing negotiations to continue for their lives. I provided them the option of giving all arcane patchworks they have to the elder brain, in exchange for their lives, which the characters said no to.... Who says no to an Elder brain?
Option 4: End the negotiations and place them in a Mind Flayer prison of some type. Most likely an intellectual prison where they spend the next few years in their own minds battling horrors upon horror, until one day, 1D20 years later, they wake up for some unknown reason. Kinda like a Matrix thing where their minds are enslaved in an intellectual prison until something happens with the colony and no one is left to maintain the prison. Or until the characters are released. Could be an interesting way to see how things evolve in their home lands as 20 years just goes by and everyone forgets the characters, thinks they've died, etc. It would change some of the other plots and stuff, but would still be interesting. I'd have to make some adjustments to the world..
Any other suggestions to offer them a way out, that's realistic to the situation, and /or not just a cheese out to allow the characters to live?
