Vaca arrives in Myto during a seasonal blizzard and immediately, following a quick meal at Mordenkaiden’s Magical Café, heads off in search of Culas of House Topaz, his missing lover. Discovering her apartment untouched, devoid of records and with only one lead – a single piece of misplaced amethyst – the shifter correctly ascertains the connection between this clue and the dwarven religious sect, House Amethyst.
No sooner has he arrived at the city’s local Stead, however, than he’s promptly asked to leave. It seems the Steadmistress, one Obuqa of House Amethyst, is very reticent to discuss the matter of Culas on official House property and implores, in none-too-subtle terms, for the fighter to meet her at a more discreet location; an antique shop on the Slope, the district that perilously overlooks the Crevasse.
Hobnobbing with a morose fool in a tavern for several hours, Vaca eventually heads towards her rendezvous and, to his surprise, encounters a particularly strange specimen – a warforged with the mind and soul of a young boy. Blessed by the power of someone he calls “Mother,” Vaca has only just made this strange specimen’s acquaintance than a carrion crawler – a repulsive beast from the depths of the Kazalhan – slithers out of the crevasse to attack!
During the conflict, both Vaca and Leviathan prove their mettle, the warforged protecting the shifter while the crawler’s paralytic poison renders him helpless and the shifter leaping into the fray to slay the beast once the paralysis wears off. Deciding to work together –more to keep Levi from trouble than anything else – they set off together to meet Steadmistress Obuqa.
In the back room of the antique shop, Vaca learns from the astral projection of the Steadmistress that Culas of House Topaz was dispatched to find Jebebror, a holy site supremely sacred to the dwarven people and lost for hundreds of years. A member of the sixth such dispatch sent in pursuit of such a rumor, all the previous expeditions were met with disaster, madness and eventually silence.
Resolving to set off after his lost love, Vaca – with Levi in tow – head to Tunneltown, deep within the Crevasse to hire a guide. After a disconcertingly poor attempt to steal a gold coin from their eventual guide, the heroes hire two delvers – Lusty Lanakhiz, the bodyguard and Ûma of House Cinnabar, the academic – to accompany them on their fool’s errand into the Kazalhan.
All that remains now is to provision and depart into the twisting, lightless terminals that stretch on infinitely beneath Eregia’s earth.
