Perhaps to Avarice’s concern, he recognizes the symbol tattooed on the woman’s hand indicates her as a cultist of Tharizdun. Also called the chained oblivion, rumors say Tharizdun was a former deity who glimpsed a shard of pure evil and instantly fell to corruption. The elder evils - as they were called - told Tharizdun to plant a seed of evil inside the Astral Plane in hopes of nurturing it until the seed grows powerful enough to overthrow the divine entirely. Tharizdun rejected, and instead planted it inside the swirling chaos of the elemental seas, the home of the fallen primordials - and each other god, good and evil, known and unknown, powerful or meek, joined forces to imprison him in an unknown amount of divine shackles. 

Tharizdun - and by extent, his followers - seek and end to all there is. Nihilism and absolute disregard for the lives of themselves and others denote Tharizdun’s followers. Their logic is inhuman, cruel, and insane - if they have any left at all. Those so deluded towards this path of destruction are often insane, suffering from some severe loss or simply vengeful against the existence which created them. These cultists seek to free Tharizdun from his shackles - and unleash his chaotic wrath upon the world. Their motto involves some sort of ritual - called trading an eye for an eye. The difference is these cultists desperately hope the whole world falls blind, as the saying goes.

The one-eyed woman, however, merely calms her breath and answers in a thankful, polite tone. “I have simply been The Bishop for so long. Call me Bishop, please,” she requests. “I…I do not remember my purpose here. I simply remember the company I was with. We have all been turned to stone. I watched them fade to dust over thousands of years.” The Bishop sighs. “I have nothing to offer besides my thanks and my abilities, which have persisted.” You watch as The Bishop raises her hand and closes her eye, murmuring something under her breath. Her hand glows with radiant, white light. She lowers her hand and looks towards the group. “I know not who to thank for my continued powers, but know my spells are at your service. I don’t think - I don’t think I can bring myself to continue on, but for what it is worth, if - or when - you return, my aid and spells are at your service. If one of your friends falls, bring them to me. It is the least I can offer in exchange for my life.”  

Avarice's eyes widen a bit as he realizes that Bishop reveres the god of insanity and oblivion. He usually didn't care for the gods and their schemes but this one sent shudders through his tiefling body. "Yes, thank you for that offer Bishop. I will have to confer with the others. Just rest for a while now." He says and  walks over to the others, informing them on Tharizdun in a lowered voice.

Hmmn.  A dark and bitter part of Varan's heart hopes this 'Bishop' escapes and releases her master to end the world, just so their righteous-but-corrupt jailor has the blood of the entire universe on its hands for keeping such a dangerous person as a plaything in its demented game.  He shakes such thoughts away.

"I'm sure all of us need some time to recover.  I propose we rest first and then we can discuss which gem to use next."

The Bishop respects your privacy - and seeing Keyleth nearly bled out on the ground, whispers a few words; a few minutes into the conversation, everyone feels a rush of positive energy as 19 hit points are restored to anyone in the room. Afterwards, you see The Bishop consoling the still-terrified Gazinoth. 

Feel free to take as much or as little of a rest as you want. 

Wulgar thanks Bishop for the healing, but has been considering her, her words, her actions the entire time.  He steps over to Gazinoth and says "We made it!  Great job!" trying to boost his spirits as well.  To Keyleth he says "I imagine you are going to want to rest for a long while, is that right?  I thought you were a goner and I couldn't do a thing to help you.  Had to go for the king instead.  Let's all have a rest."  

(Long rest?  Long rest?  Long rest it is!  With a watch set, I think...)

Wulgar takes first watch, keeping his eyes on Bishop and the room through his time, then nudges the next when it is time to take the next shift.  He goes to sleep and dreams of the chessboard, dreams of the astral plane and what might have happened if they lost.  He wakes up refreshed but startled.  He tries to recall what crystals are left and what choices are next.

Avarice takes second watch, keeping a close watch on the likely deranged Bishop. He has a fitful sleep with dreams of being trapped for an eternity in inescapable rooms tortured by hellish flames and what little is left of his conscience. When he wakes up he quickly readies himself to take on their next test.

     On his watch Mulligan will engage BB in a philosophical discussion, if she is awake.  His angle is his curiosity about why those who seek oblivion are so altruistic to want to bring it about for everyone, not just themselves.  “Wouldn’t it be easier to find a way to destroy your own life and souls or such than that of all of existence?  If you truly care about nothing then why try to bring this delightful end to everyone else as well?”

     But mainly he yawns a lot and tries to stay awake for his watch…

 Varan will take last watch (shouldn’t need more than 4 watches, right?).  He will spend most of that time pondering the nature of their jailor … the patterns it has displayed… the inconsistencies it has displayed… and work on his theories about its nature.

Keyleth takes any watch—she doesn’t need to sleep, being an elf. She splits it between wishing she hadn’t made the mistake that brought her here and giving the Bishop sideways glances, not trusting anyone with that tattoo.

The party convenes for some time, warily watching the new arrival. The Bishop appears to understand and calmly sits across the room, eventually falling asleep slumped against the wall nearby. 

Another surge of quickened time pulses through the room, and a short time later, your wounds have somewhat healed. I'd like everyone to make a Wisdom saving throw - otherwise, continue as normal. 

Wulgar wisdom save :  10 

After his turn, Wulgar wakes up refreshed, says “Which crystal should we try now?”

Avarice shrugs, letting the others decide.
Wisdom save: 20

Mulligan Wisdom save:  13

     Mulligan (if able to do so) would opine that we use the solid colored one.  It is most like the others and the one that has a stripe (or was it two colors?) could somehow indicate double the danger?

If we choose the white gem Avarice will go for cold as his temporary fiendish resistance.

Varan CON:  24

(duh)

Varan WIS save was intended… bonus is only +2 instead of +7, so using the roll above, WIS save would be 12.

Keyleth WIS save: 24

One of the gems is solid, pearly white; the other is somewhat clear. A flat, black segment divides the gem into two. 

Keyleth, you feel the weight of the rapid progression of time ache in your bones - you only regain half of your hit points for this night's rest, but you manage to regain other abilities that refresh on short or long rests, such as spells. 

Wulgar says, "What about the clear gem?  Want to try it?"
