Daoine Gloine

When Aluxis Vinstrad found it, the legendary lost city of Daoine Gloine was already an isolated mountain settlement. After he took over, the inventor set about closing off any and all routes to the site. People seeking the city find the narrow mountain passes begin to tighten around them the closer they come to the location where the city is said to be. Many of the passes, tunnels, and trails are deliberately blocked off with rockslides and other unexplained disasters. 
The city of Daoine Gloine has long been thought of as mere legend — just another strange tale from the already-strange Mortarcliffe Mountains. Occasionally, travelers would return from the mountains with wild claims of having been lost in the peaks and visiting the city by accident. And though none of them could produce a full map showing the route they took, their stories all shared a common element — that Daoine Gloine was populated by creatures made of living glass, tended to by kenku in love with those creatures’ shining beauty. These occasional tales drove more explorers — including Aluxis’s own expedition — to seek out the route to Daoine Gloine and learn the truth of who dwelled there.
As is often the case, the common tales had more sinister origins. In ages past, the kenku that inhabited the city captured a unique medusa — Gloine Nathair-Nathair, whose gaze could transform victims into glass instead of stone. A cult of the medusa arose to worship the creature, which was effectively incarcerated within a central temple. Kenku priests brought regular sacrificial victims — both willing and unwilling — to stand before the medusa’s gaze. And when Gloine Nathair-Nathair died, the kenku raised her in undeath to prolong their cult, continuing to fill their city with glass statues.
After Aluxis fled his first laboratory at the Monastary of the Distressed Body, he used the initial research of his expedition to eventually make his way to Daoine Gloine. But instead of being welcomed and allowed to work in peace, Aluxis found the city’s evil high priest threatening to transform him into Daoine Gloine’s latest art installation. Desperate, Aluxis constructed another planar gateway while imprisoned in the temple, then opened a portal to the 222nd layer of the Abyss — Juiblex’s Slime Pits. A flood of ooze issued forth, driving the kenku from Daoine Gloine and effectively sealing the city away from the rest of the world.
The entire site — including the entrance to Aluxis’s second lab — now spreads beneath a deadly layer of clear gelatinous ooze — perfectly preserved, eerily staged, and utterly devoid of anything organic. The kenku that once occupied Daoine Gloine have all long been turned to glass or driven out. The city’s only resident was Aluxis, who himself was trapped in stasis until the arrival of the The Guild Pact. Since his return, this city has remained mostly empty as Aluxis Vinstrad has returned to living with his disciples at the Monastary of the Distressed Body.
