The rocky cave (also known as Virgil's laboratory) is a location in the Commonwealth in 2287. Virgil has chosen this cave as his refuge, as it is deep within the Glowing Sea and out of the Institute's grasp.


The cave entrance is a small cavity in a larger rock structure that opens up to a wider passage. At the end of the passage lies an opening, guarded by turrets, to a chamber that has been furnished with laboratory equipment and a small living quarters.
