We completed the battle against the (long-dead) "Faulleen king" zombies, and proceeded to the chamber from whence they came. A funerary with several biers — probably where the zombies we just fought came from — and murals of the five elements (lightning or raw magic apparently is the 5th element…). A door (Tiberius very professionally picked the lock) lead to a treasure vault! There was a large mound of silver pieces — Ty shoved as much as he could carry in his old backback, which turns out to be 1,200 s.p.
There was also some shiny breastplate armor (claimed by Maximillian); a lovely suit of splint armor (now worn by Callan); a cool-looking silver amulet; a finely-made warhammer; a hand crossbow (which Ty enthusiastically grabbed!) accompanied by a magical black-and-green quiver for hand-crossbow bolts (bolts extracted from the black side are regular bolts, those pulled from the green side are acid bolts).
We secured the door and took a short rest in the vault.
Moving on, we found a very long corridor leading east: we estimate it leads to a space underneath the chapel between the water flow and the lava flow. The passage ended in a transparent wall — we could see some kind of funerary operation on the other side, a woman and some workers preparing several dead dragonborn for some kind of ritual. We found a way to open the wall of one-way glass, and Sheefra charmed the woman. We asked her how to find the manticore: we must find the "Hall of the Faithful" — but first, we must each touch all 6 elemental pillars! (earth, water, wind(air), fire, electrum, and 'divine' power)
We went all the way back along the underground passage we came by, to the Ironforge. We proceeded directly to the nearest pillar: the earth pillar, which was guarded by a wood-wode; and dangerous muck covering the bottom of the crater in which it stood. While some braved the muck (Max made dutch-style clogs), Sheefra cast fly on a few others (Ty licked the obelisk when he was carried by it).
We marched over the bridge over the lava flow, on our way to the water pillar: some mutant-things, including alphas and gammas, were guarding the bridge…
