The Stone Basilica is the site of ancient Dwarven ruins deep inside Sorrow's Furnace. The Basilica is a towering structure of stairs, pillars and archs that can be found through the right most (south) door upon entering the Furnace.
The Stone Basilica is the site of the following quests in Sorrow's Furnace:
- Summit Slaves: It is to be scouted for the Deldrimor Dwarves.
- Unspeakable, Unknowable: It is the site of the ancient Tome of Rubicon. High Priest Alkar destroys the Tome on top of the Basilica.
The basilica is the location of Molachev, if players enter without taking any quests.
