Ghurr's not entirely sure what he's seeing but his curiosity keeps him going. Just before he steps through though, he takes a closer look at the image of the smaller room. Does it look prison chamber like? Small bedroom? Empty chamber?

Standing at the threshold of the portal, you see a little more of the room. It is another octagon shape, with 8 archways, similar to the ground floor, though much smaller. It looks almost entirely empty, though you can now see a second door in a wall to the left. 

Gaudy floral patterns edge the room, but it is otherwise plain. The arches and doors don't leave much room for other decoration.

It appears to simply be a space providing access to other rooms.

Ghurr pauses and looks back and down at Faera,.

"Do you see other room?" Ghurr asks. "Like smaller version of this room. Mom asked plants to make maze once. Ghurr get lost in it for days. Should we still go through? Ghurr not find way out of maze but if Faera come then sure will be okay."

(Assuming Faera does see what Ghurr does)

She smiles up at Ghurr as he recalls his mom's maze.  "Yes, let's go through, of course I will come with you."

 (She does, as do you all.)

As the others walk through the portal,  Mala follows. Once see passes through she quickly scans around the place.  (Perception: 25)

Thurodim grunts and follows the others.

Stepping into the small room, this is the space you see (more or less, within the confines of my ability with Inkarnate):

Now that you are in the room properly you can see that there is a third door immediately to your right, out of your field of vision while you were in the entrance hall. Otherwise, all is as you saw through the portal - another floor mural, pointing to eight archways, three doors, minimal decoration.

I have circled the archway you came through, and put arrows to the three doors, in case they are hard to make out.

Thurodim walks the perimeter of the room, checking and listening at the three doors.
Perception: 11
As he returns he looks to see if he can simply step back into the entance hall or not.

At each door you hear only silence.

As you last of you passes through the archway, the image of the entrance hall fades, leaving only the same stone wall that surround the rest of the room. Pointing towards the now empty archway is a new symbol. Those who understand Elven recognise it as the equivalent of the letter 'E'.

Scratching his head over this strange place, Thurodim tries to walk the same way back, walking over the symbol the same way Ghurr did in the entrance hall.

Thurodim's experiment has results - repeating the actions repeats the effect. The archway through which you came shimmers back into life again, a portal back to the entrance hall.

Excited that he seems to have figured something out by himself, the massive green half-orc fist pumps with his free hand, glancing over at the others with something resembling a wide smile. "See, we can get out." He rumbles, but then gets a worried look. "Which means the evil in here can too. We can not let that happen." He rumbles, his grip of Skullcleaver tightening again. "Do you want to look at the star or should we try one of the doors?" He asks Faera, who he considers in charge of the arcane part of the investigation.

Ghurr smiles at Thurodim. He then counts on his big furry fingers until he gets to the fifth finger. 

"E as in exit and entrance," Ghurr says.

Then he looks around the room.

"That would not be very good prison if knowing alphabet was all it took to escape."

Ghurr moves over to the door right next to the "E" gateway. If Thurodim doesn't hear anything, Ghurr will see if the door is locked, and if it isn't, open it and look inside.

The door is not locked, and opens into the room. Stale air wafts out, with a hint of old rot. Through the doorway you see barrels to your left, and on the opposite wall shelves heaped with indiscriminate grey/green shapes.

Thurodim nods to Ghurr and steps inside the next room, Skullcleaver firmly in his massive green hands as he checks it for threats.

He watched in silence as the strange situation of the tower was solved and the group could enter it. The first thing he noticed was the not so discreet painting, a thing that elicited comments and questions from his companions too. If this is the embellished version I cannot imagine how the man looked in person. 

“No idea about who he is, but his ego should have been enough to get to reach Eumora from here.” Faera was less subtle and more honest with her assessment of the spellcaster’s image. “And I second Ghurr.”

The elf mentioned as the bugbear suggested taking the lead, a suggestion the wizard accepted. Soon enough the advanced duo called for the rest to follow and Ilithir did so with arcane focus on hand.

“I would have liked to say that maybe the thing imprisoned in here is bound by another way, but since our friendly apparition suggest the chance of it escaping, you seem to be right.” He mentioned to Thurodim. Clearly they were the two optimistics on the party. “At least nothing is trying to ambush us. I have an item that prevents me or any ally until thirty feet from me from being surprised.”

The best purchase of my life, he said with the voice of his mind.

Those of you who know the Elven script (everyone except Thurodim), might consider the discrepancy  - if the E does indeed stand for Entrance, or Exit, then the Elven script is being used for a Common word. Elves have their own words for Entrance and Exit, and they do not start with the equivalent of E. You might suspect that the person who designed this place, with its Elven script and pastiche of Elven decoration, is quite pretentious, like an English speaking person scattering their conversations with Latin phrases because they think it makes them sound smarter.

Thurodim now in the room sees this:

The grey-green shapes on the shelves appear to be the decayed remains of food, centuries old. The stillness of the air in this closed-off place has maintained their shape somewhat, and you can identify things that probably were once meat, and others that may have been vegetables, or fruits, or cheeses. But mostly it has all rotted into a single mass, long beyond the point where it would even smell terribly bad, though the essence of it hangs on the air.

Not too bothered with the stench, he had smelled worse himself, Thurodim quickly scans through the room for anything out of the ordinary.
Perception: 23

All seems pretty ordinary. An old storage room, barrels and shelves filled with centuries old rotted food. But...

The gently furred, grey-green slime that is all that remains of the food seems to be pulsing. Almost like a heartbeat. Your mind flashes with a sense of danger, and something like a tentacle reaches out from the food slime, right for your face!

For the sake of expediency, Initiatives:

Thurodim: 16

Food slime: 18
