The Shadow Marches
The Shadow Marches are home to most half-orcs. The country is home to mostly orcs and human families, with a few half-orcs. The families are part of clans, made up of both humans and orcs. House Tharashk operates from here, and consists of a fairly loose group of humans and half-orcs. Eberron Dragonshards are found in the Shadow Marches.
