It's been 24 to 48 hours so I'm going to proceed and if Zenodor doesn't wish to go through the portal he can post what other course of action he takes.

You all go through the portal and emerge from an ancient stone arch with mysterious arcane sigils and runes etched upon it in various locations. The landscape that greets you leaves no doubt that you are on another plane of existence as there is mostly shades of gray and different levels of darkness and shadow, any trees you see remind you of winter as they are leafless and just bare branches, and a chill wind is blowing but its currently not very strong, just enough to cause your hair to flutter and cloaks to billow from time to time. The sky overhead is pure black, not only is the moon missing but there are no stars in the night sky.

You currently see no buildings or structures of any kind and no people or animals in this desolate wasteland.

 "This seems a very bleak and remote place. Do any of you know what or where it might be?"

Arcana roll for knowledge about this plane 6

Tempe looks around thinking upon his monasterial teachings. 

Pepin hasn't travelled or studies different planes of existents so doesn't know anything about the plane they suddenly find themselves on.

Tempe, you recall from hearing a wizard once say that a plane existed of pure dread where all hope was lost, it was called the Shadowfell!

But if that were the case you should be in a shadow version of Laurentiis and instead you are looking out over a wasteland.

Randall:

Turning around and looking at the gate and its sigils, Randall tries to discern if there are any clues to their current location written in the stone.

Arcana:  9

He then looks around where they are, checking to see if the mages left any trace of their passage.

Perception:  16

There are several clumps of dried and squat plants scattered all around, what would have been lush green bushes back home, it has been so long and dreary here as the days follow each other and dullness and gloom try to take hold of your very souls.

Can everyone please make a DC 15 WIS save.

There are broken pieces from some of them leading North, into the low hills which is mostly rocky terrain and the scattered sparse tree. It's very likely the last person to pass this way went North.

(Recall, Beacon of Hope gives advantage on Wisdom saves)

Randall’s Wisdom Save:  27

Pepin wis save: (10, 4)-> 10 +6 flash of genius for a 16
