Let me back-track a bit:
When Delver passed through the screen, Tybalt executed a Jaunt, but was suspended in a 'buffer' of a nebulous milky-white light where he had the conversation with the voice.
I took Delver's player outside and explained that dying now would satisfy the bargain presented to Tybalt, that it would avert a danger that if he were present would be dire enough to cut the Threads of the rest of the party, and that the found non-magical sword (not detailed in the previous post) would house his entity until the blade were used to slay an, at least, human-sized creature from which he would reconstitute his body. This process was necessary for his eventual manifestation of his Avatar, an Aelbaan species meta-power.
--He agreed.
I was greeted by Tybalt's player who then whispered that he was beginning to study Delver's character for 3 Rounds, as per 'waylay.'
Delver consumed his entire Dynamic Pool to telepathically call out to his compatriots to kill him for the above stated reason, and most of them obliged him.
--Their purses were heavier by d100 Platinum (ultra-rare).
The rest of the group then watched as Ashta took control of the craft.
They took the craft downstream as a whirlpool began to form (they chose not to investigate the source), and after a day of travelling, ran afoul of a giant aquatic variety of a Grell-like thing from which they fled down another opening and entered another section of the craft, clearly dedicated to dark practises. This area sloped upward and after they discovered how to operate the crackling 'electro-riser,' they eventually left it behind in the narrowing corridor carven with figures and reliefs too darkly mesmerising to detail here.
--Eventually, they blasted through the doors of a temple and came to rest.
Alighting, they entered the temple replete with additional figures, pillars, implements, and a low and high altar. A swarm of two-dimensional, light-absorbing, flying things flew out from among the toppled pillars and buckled ceiling and floors, but the damage was only spooky to one character. Ashta gave a polite order to Mela to begin the mummification process upon Delver's cadaver, which eventually would yield 1 cup of dust from 1 gallon of slurried sediment. Shadow creatures, illusions, and/or Dryvv speak with them and then Lord Shadow deigns to manifest, asking for a sacrifice.
--Tybalt, the Shadow-blooded (also exploring shadow-mysteries), was attentive and they finally settled upon Delver's mummified body (minus the stuffing which constituted the 'dust' reduction), which pleased the Elemental Lord. Tybalt's reward was a potion that would allow for limited planar travel, so long as the start and finish were in shadow, and that the elemental plane of Shadow were the conduit. He also learnt additional shadowy stuff.
With that over, the group left in the vehicle and encountered a stretch of lava tube that was encrusted with fungi that cast beautiful light in the Dark- and Ultravisual spectra, as well as a lesser show in visible light. Samples were taken and critters caught for specimen. They pressed on and saw daylight and a storm over the open seas beyond the island from which they emerged --clearly a different island from the one they had entered the underworld.
--They performed an initial survey of the coast, using the Aelbaan vessel's sensors and recording suite. They noted ancient dwellings in the sheer cliff face overgrown with vines and runners. three-quarters the way 'round the island (larger than the previous -- and believed to be the pod-island) they could see signs of great upset in the jungles and forest as trees were tossed-about while some great battle of beasts was waged out of sight.
We held it there.
