"I didn't do anything. I am pretty confident you were dead Sarith... I am confused. What kind of magic is that?"
OOC: Would Grimnir knows anything about how Sarith could back to life?

Grimnir is growing suspicious with Bupido. Since the start, he never really trusted him. But these last days, he acted more and more out of the ordinary. He attacked Stool, was left with the Dwarf who got sacrificed and seems happy to see us struggling. 
OOC: can I insight him when he talks about Hemmeth ? Insight 7

"Yes I think camping for a while might be useful" 
Perception 11

Meanwhile, Oorr and Zippy stand on watch and eventually set camp.

Grimnir and Belwar:

 Sarith replies to Grimnir, "Magic? I don't know what you're speaking of. I must have simply been unconscious. I feel fine now, but let's rest, and hurry to Gracklstugh, we can't be that far away. I want to get Stool to the Neverlight Grove soon, but we need supplies." He begins to stand up, gathering his things that had fallen, and heading towards Oorr and Zippy. 

Grimnir, you don't let it show, but you're certain Bupiddo is hiding something. He knows more about what happened to Hemeth than he's letting on, but he's trying to distract everyone with the urgency to get to Gracklstugh. Sarith also seems eager, but he is more honest in not knowing how he was revived.

Collectively, you all gather your things and begin to head where Oorr has found a safe place to camp, knowing Gracklstugh is near.

(OOG Everyone gets 350XP from the Grick fight. We'll assume you are taking a long rest now, and you can level up to Level 4, and make any adjustments you like to your character sheets. Feel free to update anything from Xanathar's if you like, or swap spells, etc. Anything that isn't equipment related, feel free to update.

Fell free to continue asking questions or playing out the current situation as you rest, and we'll move on when you're ready.)

"So... Is there any exit from the Underdark at Gracklstugh?" Valrish says, cleaning his mace and fiddling with the gems he still keeps from the drow settlement. "I don't mean to hurt any of you, but I'm really getting sick of this place..." He mutters, giving quick glances at Derendil and Buppido.

Before heading to sleep, Oorr focuses on his primal magic to detect creatures from other planes.

Primeval Awareness

Beginning at 3rd level, you can use your action and expend one ranger spell slot to focus your awareness on the region around you. For 1 minute per level of the spell slot you expend, you can sense whether the following types of creatures are present within 1 mile of you (or within up to 6 miles if you are in your favored terrain): aberrations, celestials, dragons, elementals, fey, fiends, and undead. This feature doesn’t reveal the creatures’ location or number.

"I've also been getting a bad sensation from him... I'll see what I can do." The dragonborn keeps on cleaning his weapons as he looks from time to time at the derro.

"Better be careful during the watch. Elementals, aberrations and fiends are within 1 mile of your position. I can take that first turn with Zippy."

Griming is talking to Oorr, Valrish and Belwar... " I don't know about you, but I would prefer if you don't leave the watch to Buppido for the rest... I don't trust him. Let's share the watch between us 4 my friends"

"Zippy and I agree on that."

"I think the encounter with the Prince of Demons or the Faceless One might have had a lasting effect on him."  Don't name names; can't be too careful. 

"I'll stand first watch then."

"Second." 

"Zippy and I go third, then."

"I'm not particularly good with demonology but isn't it a bit weird that the Prince of Demons is having a stroll in the under dark ?"

"Yes.  Very." 

By keeping an eye out for both threats from without and within, and taking turns keeping guard, you all manage to make it through the night, gaining the benefits of a long rest. Bupiddo remains fast asleep through the night, clutching the dagger that now never seems to leave his hands. Though you hear and sense the movement of creatures around you, you do not see anything approach your camp, with one notable exception... while Oorr is on watch, he hears a familiar voice in his head. "I... came as soon as I... could."  Glabbagool has finally caught up with you. 

Sarith gets his bearings in the morning on the direction to travel, you all forage for food and supplies, and then strike out through the Underdark for Gracklstugh. Though initially wary of the gelatinous cube, the party accepts that he seems far more intelligent than the average ooze, and he is welcome to accompany you (If you still wish. Glabbagool will leave if asked.) You spend the next several days traveling without incident, a long plodding walk through various caverns and tunnels in near darkness. You travel slowly enough to let Glabbagool keep up, which turns out to be beneficial. You notice a roving band of goblins, and are able to avoid them, as well as narrowly avoid a patch of green slime dripping onto your path.

(OOG Let me know if there's anything specific you want to do as you approach Gracklstugh in this last leg of the journey.)

In the middle of the day, on what Sarith assures you is very near Gracklstugh, you round a corner and encounter a mind flayer. Several of the party immediately grab their weapons, fearful of what they know to be a dangerous creature. It appears to be reading a map, unrolled on a parchment. He looks up, noticing the large group, and his voice pushes into your minds. "There, there, no need for the fuss. I'm just a little lost. I could have sworn the teleport should have taken me closer to Slubloodop... Say, do you happen to know where we are?"

"Theoretically, we're almost at Gracklstugh," I reply in Undercommon.  Then, as an experiment, I think it at him.
