A metallic disc sought by Gulpax the Crafter to build her Construct guard Alpha-Zero a new body.

“An artifact of extraordinary power. This is why Gulpax sent me into the hive. She says she needs it to build me a new body.” - Alpha-Zero - The Hive (GS-ADV3)

Found in the Sacred Caverns of the Insectoid Hive, it has the power to translate languages from a bygone era;

One of the Insectoid priests consults the runes printed on a small metallic disc to help him translate the ancient texts. - The Hive (GS-ADV3)

Alpha-Zero plucks Revlar's Disc from the sanctuary:

• Tell her to return the stolen object:
  • Take back the disc from her possession and earn the gratitude of the Insectoid priest, to Alpha-Zero's dismay.
    • Steal the disc again after Alpha-Zero recounts Gulpax's need for it.
• Aid in her exit before she is caught.

This is why Gulpax sent me into the hive. She says she needs it to build me a new body.” - Alpha-Zero - The Hive (GS-ADV3)

If you return to the Sacred Caverns with Revlar's Disc in tow, the Kobold priest Khathandor will engage in combat with you:

• Dispatch him, and successfully keep the disc.
• Fall to his blade, and return the disc.

If the disc is in your possession, Alpha-Zero will be able to use it for a power boost as she prepares for the upcoming battle.
