The Glowing Sea Main Story Quest

1. Find Virgil in the Glowing Sea

I need to find Virgil, the escaped Institute scientist, in a cave southwest of the crater in the Glowing Sea and hope that he can help me reach the Institute.

Go to the Edge of the Glowing Sea, then move to Crater of Atom ant speak with Mother Isolde and ask her about Virgil - He is hiding in the Rocky Cave.

Make a save game outside the cave. Enter the cave and DON'T attack anything (turrets, robot), go inside and talk to Virgil, he will tell you how to get into the Institute. If he is hostile, just reload :-)

2. Quest completed

I spoke with Virgil, an Institute scientist who willingly turned himself into a Super Mutant to escape. He's told me that the key to teleporting into the Institute is a chip from an Institute Courser. I'll need to track one down and kill it.

Next / new quest is Hunter/Hunted (Main Story).
