A dungeon expansion for late game Lost Mines of Phandalin. An ordinary-looking cave nestled in the northern foothills of the Sword Mountains west of Phandalin hides a dark secret. Many have sought the power held deep below the surface, and none have left unchanged.
The caves conceal a long-abandoned Drow outpost and temple, left in ruins by the passage of time, looting, and the relentless advance of nature. A dark power still clings to this forsaken place, enticing those who yearn for power or knowledge to venture into its depths. This dark energy has scarred the very fabric of the area. Winds rising from the bowels of the caves carry haunting whispers—echoes of the past horrors that took place within the temple of Lolth. As these whispers beckon, adventurers must decide whether to heed the warnings of those who never escaped or to venture forth despite the risks.
This expansion provides a hook to add a second stage to Wave Echo Cave’s Nezznar (Black Spider) encounter. It also provides some breadcrumbs to a second encounter with Iarno (Glasstaff) Albrek—assuming he is still alive.
Encounters are balanced for four 4th-level characters (2024). They are challenging and potentially deadly if your players rush in, so adjust accordingly.
