"If we're leaving, better to leave while we can I guess," Kastix states, "I would like an hour some time before day's end if no one wants the staff to get used to it,"

(Im somewhat regretting not taking a feat instead of score ability now)

Deciding there is no time to lose, the group quickly pack their belongings and make their way back through the guard posts into the city proper, crossing to the west side and approaching the cavern of the stone giants. This time nobody is in sight, and with no door to knock on, Sekkar calls out a summons, his sibilant voice echoing back from the empty tunnels (how does a sibilant voice echo?)

After a few moments of waiting, the rumble of footsteps heralds the approach of Hgramm the Stonespeaker. Greetings, comes gravelly voice in Undercommon, and a welcome return. I am sorry I cannot entertain. Another of our number has fallen under the curse of two-headed madness and I must attend them.

Pax watches the giant with a bit of trepidation, and waits to see how the group responds. 

"Greetings Stonespeaker Hgramm. I hope that The Lady... I mean The Moonmaiden may aid you." Rhayna says with a low bow, the she looks at the Stonespeaker. "We are leaving Gracklstugh with haste. We came here to warn you that Themberchaud is free of his shackles, and he is no longer under control of the Keepers of the Flame. He said that he will burn half of the city, and told us to leave immediately. We are trying to make our way to Blingdenstone after we speak with you." Rhyana tries to impress the severity of the situation.

Zeno adds, “Oh, and uh, some derro and outcast Duergar were worshipping demons and trying to use you guys to destabilize the king or whatever. They’re responsible for the two-headed thing...“

Kastix is just staying a distance and letting those involved with this handle this. 

Hgraam listens with a stony expression (!) and stands rock-still for a moment in thought before answering in his slow ponderous voice: Truly I said when last we met that your coming here is as a tremor through the bones of the earth. These are grave tidings and fell times for my people. But we are sworn to the king, and so we shall warn and defend him against the dragon's wrath. This doom is greater than that of the derro. Well it is that you should flee, but conceal your haste lest the Stone Guard find cause to apprehend thee. Go now.

Then facing Rhayna, the stonespeaker adds: I trust you will retain my gift. The day will come when again you seek the libraries of my kin, and then it shall serve you well. This is what the stones tell me.

"I believe that is the decision you would reach, to be true to your vows, but we believe that at the very least we should warn you of the perils ahead. I hope that we will meet again, Stonespeaker, please do take care of yourself and your apprentices." Says Rhayna sadly. "I shall take care of your gift. As a matter of fact, the crystal aided me in receiving the Goddess' warning. And thus, we are trying to leave Gracklstugh as soon as we can. We will try to be careful on our way out. We again, thank you for your council." With that said, Rhayna motion to the myconids that it is time to leave. Rhayna is so sad that she didn't even show any emotion at the mention of a library.

(OCC: Stony expression. LOL)

Kaylyn stands back during the interaction and only observes.  She keeps an eye out for trouble.

Pax sucks in a deep breath, "Right. Well.  Good job all.  Now, let's go find our guide?"

To Sekkar's opinion informing the giants about plans of the Dragon was a mistake - "demon-worshipers are turning your lot into the monsters to bring chaos to the city" had to suffice, but what's done is done, he just hoped the group was not going to announce the big news on the main square. "The guide and the fast run, agree." He was just waiting for Zeno to show the way to the guide.

Zeno nods at the others in agreement. “Let’s go,” he says, and he leads them out toward the gate.  “We may need a plan for getting past the gate guards. Like the Stonespeaker said, they may look to hold us for some reason.”

"I don't know how tight lipped giants are but I think we should get out of range of a big possibility angry dragon as quick as we can," Kastix whispers as they want away, "If the guards want to keep us, can turn two of us invisible to help get by," 

(Invisibility at 3rd level (+1) or twinned spell (+1))

(Kastix: you may nominate someone else to turn invisible. Your choice.)

The last of their errands having been run (besides reporting to the Guard captain), the group make their way hastily (without appearing to look hasty) to the city exit. Tentatively they approach the gate, guarded by two visible duergar but who-knows-how-many invisible duergar, and flash their badges, perhaps looking a little too long or too nervously into the dwarves' faces. Wordlessly the guards admit them through the gate, watching the group closely but apparently remembering them, or recognising and giving respect to the badges, or any number of other possible scenarios. With bated breath, each member silently passes through and on into the derro slums.

As before, the derro largely ignore the group, more due to being preoccupied with their own mad business as from any desire to avoid confrontation. The loose paths pick their way erratically through several hundred feet of ramshackle hovels and random detritus before petering out, and before long the group find themselves back in the long, silent, lonely, dark tunnels of the Underdark - a strange juxtaposition of claustrophobic passageways surrounded by miles of rock, and the sense of endless expanses of nothingness.

Taking a quick rest to ensure none have followed and to count their lucky stars, the group gather their things and move on. The tunnel stretches unbranching for a considerable distance, and the group have travelled for almost half a mile when each hears a familiar voice booming out of the darkness. Halt! I have not given you leave to depart. You have failed to give a satisfactory report, and worse, you have corrupted my dragon. You will return to Gracklstugh and stand before the Deepking to be judged.

Everyone please make a Wisdom saving throw. Kaylyn, Pax and Zeno can roll with advantage.

EDIT: Then everyone please make a Perception check, with disadvantage if your Wisdom save was less than 14.

(Probably turn Rhyana Invisible as keeping Cleric safe would be good and this is assuming Zeno can get out on their own)

Kastix Save: 16
(If I fail, add 5. This is strange effect as I can do after learning if I failed)
Perception: 5

Rhayna WIS Save: 10

Perception (disadvantage): 12

Rhayna discretely asks Stool to use his spores on the party.

Zeno WIS Save (Adv): 19

Perception Check: 18

Zeno throws the hood up on a new cloak which you all noticed him wearing when he returned, shrinking back into the darkness of the tunnel.

30

Sekkar Wis Save: 4

Perception: 15 (or +6 to that if we are in the tunnels already for the favorite terrain)

wisdom save : 16. w/ advantage thankfully : 2 ...... OMG.

Perception (Da) : 12

(sigh)

Pax looks around, "I think I heard something.  A voice or something.  Did you hear that voice?"  She pulls off her helmet, the metal shell and chainlink mask must be interfering with her hearing.

WIS saving throw 23

Perception 10
