Shadow Realm

The Shadow Realm is the fictional world seen in the Blades of Light and Shadow series.

Geography
The Shadow Realm is a hellish landscape, covered in darkness and overrun by ruins shrouded in death and terror. It is theorized that it is a dark mirror of the known world, symmetrical but tainted with each being here having an opposite there. It is also theorized to be entirely different, with unimaginable horror. In the Shadow Realm, magic is wild, unconstrained, raw, and tempestuous. Time also moves differently, where a second may be a week or a year, or a month may go by in a minute.

The Shadow Court Fortress was where the Dreadlord and the rest of the Shadow Court resided. It mirrors Whitetower in Morella.

Whimsywood
Whimsywood is most likely a forest, and the opposite of Deadwood.
