The hidden headquarters of Cynker, a mastermind of dimensional travel who has achieved paragon attunement to force magic. His lair is home to clawed nymph and rusalka-like creatures with adept control over force magic—likely his creations or servants. The convergence of force and void leylines at this location allows Cynker to manipulate dimensional boundaries, enabling him to pull off impossible heists by teleporting objects (and himself) across vast distances or even between planes.
The den itself is protected by spatial distortions and force barriers that make approach nearly impossible for those not specifically invited.
