Doing so they descended obviously deeper than the sub-level they'd recently explored. Whether this means they're on a level roughly parallel to the sub-level or even further down is still unclear. Not long after doing so they had to contend with some giant spiders, a seemingly common menace in Dwimmermount. Having defeated them, they then set out to map as much of this new level as they could, to get a sense of its size and relative relationship to the levels above. In short order, they discovered that the level seemed quite extensive, with lots of chambers and twisting corridors that went in every direction.
They came across several statues, images, and bas-reliefs that showed a similar image -- a bearded human man -- that they took to be representations of Turms Termax, the mysterious god of magic worshipped by the ancient Thulians and whose cult survived the fall of the Thulian empire into the present day. Other oddities they encountered were:
- A topographical map of what they assumed to be the entire world, with Dwimmermount at its center.
- An obelisk with strange glyphs written on it
- A collection of metallic "scrolls" that used the same strange glyphs
- A pumping machine that seemed to be processing the black oil into silvery "coins" that were then dropped down a chute to a lower level of the dungeon.
- A symbol of a three-lobed, burning eye
This was one of those sessions where a great deal actually happened, but its events are hard to relate in an intelligible fashion to anyone who wasn't there at the game table. Indeed, I suspect that the significance of this session will only become apparent later, after the characters have correctly identified the silvery-black oil. That's the focus of the next session, which I expect will be much more heavily focused on events in the city-state of Adamas ...
