There are worse things than dying

The passage to the afterlife is one of the most universal experiences - all mortals will go through at least once, and some particularly lucky ones may make the journey several times. It needn't be at the moment of death either, some meditative practices allow the user's soul to quickly nip over to the other side and be back before their tea's gone cold.
Religion isn't a factor, nor age nor power. So long as you were born or made on the Material Plane (or its close neighbors), and have the intelligence required to make self-aware choices, you're an ensouled creature. When you die, your soul flees to the Astral Plane, and makes it way to Pharasma's line.
However, this was not the fate that awaited Stot and Roark upon their untimely demise. Instead, they were met by an angel of silver blue flesh and black-iron armor, who smelled of lantern oil. She told them that as champions of Lycia, their fate had already been chosen. "You have served well, and now may rest"
They were whisked away to a strange place - a dreamlike vision of the Staglord's castle, but with a towering absurdity of stone and crumbling geometry reaching up beyond the clouds. The land looks right, withe the gentle slope up to the castle then down to the Shrike river and the Tusk, but beyond that just more clouds as if the very land itself was evaporating into nothing.
The angel was nowhere to be found, nor anyone else. Just Roark, Stot, and about a half a square mile of inconsistent terrain. It was peaceful, unnaturally so. The soft light, warm air, and calmness of the plane felt like a cold drink after a hard day's work. Wherever this place was, it was certainly restful.
There really wasn't much to do. The castle was a ruin of improbability and uncertain gravity, and impossible to navigate. The land itself stopped in a haze of impassible silver steam, and digging holes didn't seem to do anything more than pass the time. 
Inspecting the castle and nearby fallen rocks showed a lot of iconography like that found at Peggy's temple, and the other strange temple - images of a woman holding a spear and wearing a faceless helm. The one thing Stot and Roark could be sure of however, is that the area was slowly shrinking. It was slow, but sitting near the wall of silver haze showed it slowly encroaching on the castle. Millimeter by millimeter, the land was evaporating.
Before they could investigate further however, they found themselves drawn back to life, safe for now.
