First of all, let me say that what follows will be confusing. It’s a confusing thing to explain, and on top of that I’m probably not the best equipped linguistically to do it… but I’m all you got. I did draw a diagram that may help though, so hit that up for a full version.
Picking up moments after the end of the last session, the group was on the move, weaving through “The Mounds”, an area peppered with large piles of earth excavated from a newly dug tunnel which they quickly stumbled across.
Descending into the tunnel, the eventually arrived ‘under’ the mass of land that now occupied this dimension. As they neared the exit, gravity seemed to gradually shift (reverse) – so though they were underneath the land mass, they were now standing upright with a new “sky” above them. On this side of the landmass, as it was ‘scooped’ from Havenshore, it rose in elevation to a peak in the middle, atop which stood what looked like a tower.

Quick diagram
They made their way there killing a patrol, and dodging others on the way. What they discovered was that the tower was actually a building (essentially upside down) – it was deep enough in the earth to extend through to this side.
Inside, they ‘ascended’ a spiral staircase to the top (aka basement… confusing yet?) where they found the man they had been looking for… Merrik.
The basement here had no ceiling – it had been destroyed it seemed. Above them the murky atmosphere (which was close to them here) swirled and within it, they could see Merrik’s ship… as if above them was a portal through which they could see it. Part of the ship extended into this realm, though it looked as though it had been destroyed on this protruding end.
Merrik was kneeling near a black stone that sat upon a table in front of him. Near him was a bell, and next to the bell an older man lay on his side – maybe dead.
The group confronted Merrik, who was near death. He tells them they should run. Kelvyn touches the black stone and immediately drops to the ground… zero hit points. We run a mini skill challenge as his essence returns to it’s home within Califane’s realm where he remembers that this is his real existence… that Kelvyn is simply a form given to him to push the will of Califane. He decides to fight his way back to the form of Kelvyn and faces trials to accomplish this (the skill challenge). He does well, which helps give him a bonus to the death saves he is about to attempt. He will get three rolls and he needs to succeed on 2 of them!
He does, and recovers with one HP in time to see the group suddenly assaulted by a large demon. For a brief moment, he associates the demon with a name… Kasyn… but the thought is fleeting, and all memories of the other existence he has is gone, but the name sticks with him.
The group kills the demon, the atmospheric ceiling descends down upon them, forcing them through the portal and on to the deck of Merrik’s ship which seems to have crashed onto the streets of the 5×5 block of Havenshore they had made their way around earlier… only now it was back in it’s place in Havenshore (still very much destroyed for the most part though).
The group stood from the deck taking in their surroundings where we concluded the game.
