Planes associated with Eldeen

The following is in relation to the mainfest Zones close to the Eldeen Reaches

Lamannia, the Twilight Forest, is a realm of unbounded nature. Plants and animals, magical beasts and elementals,
and wild outsiders of bestial and elemental aspect run free
in its verdant forests, rolling plains, and soaring mountains.
Farmers say that crops grow more quickly during the
one week every year when Lamannia draws close.

Thelanis, the Faerie Court, is the mysterious home of the fey. Tales speak of travelers drawn into its eternal
twilight, emerging after what feels to them like mere days,
only to discover that weeks or even months have passed on
the Material Plane. The influence of Thelanis is said to be
strong near faerie rings and faerie mounds.

Xoriat is the Realm of Madness, home to the daelkyr and the aberrations they spawn. Ten thousand years ago,
Xoriat drew close and the daelkyr invaded Eberron, until
the Gatekeepers finally sealed all connections to their
insane realm.

Mabar is the endless twilight.
