Convergence

Convergences are points where ley lines converge, forming a web across the Surface. The division between the Surface and Shadowfell is at its weakest at Convergences, and as such, they are often entrances into the realm.

Convergences are extremely important to Seekers, allowing them to protect humanity by guarding certain points. Accordingly, the town of New Essex, Massachusetts, was built on a Convergence. They are capable of being sensed by Seekers, for whom it feels independent of time and space.

New Essex
The first Seeker settlement in the New World was built on a Convergence. At the exact point of the Convergence is an ancient, gnarled tree.
