The Knighthold is an underground stronghold containing a Veil Gate.
History
Before Third Cycle
Sometime before the Third Cycle it housed an organisation of knights. The inhabitants were turned to stone statues when the World-Eater broke free and ended the cycle.
The armor worn by the last remaining knight was eventually corrupted by the World-Eater.
Due to shifting during cycles, the position of the Knighthold has changed several times.
Third Cycle
Sometime during the Third Cycle the Knighthold was discovered by a group of adventurers containing The Curator who recovered the Last Knight’s armor.
Fourth Cycle
In the Fourth Cycle, the Knighthold was found again by The Curator and then visited by the Artifact Adventurers following the recovery of the Last Knight’s Set (now known as “The Ancient Artifacts”). At this time the Veil Gate was opened causing The Reshaping.
After the Reshaping
The location of the Knighthold shifted yet again with the Reshaping and has yet to be rediscovered.
