House Tharashk is a human and half-orc dragonmarked house that has just recently begun spreading throughout Khorvaire, though it is still heavily based in the Shadow Marches.
House Tharashk possesses the Mark of Finding. This mark grants various magical benefits related to locating people and objects. House Tharashk has just recently turned this into a widespread business borrowing a page from House Sivis gnomes. Now they excel in locating precious ore veins in mines as well as Eberron dragonshards.
