Scale: 12 (multiregional/kingdom). House Tharashk operates all throughout the continent of Khorvaire and is beginning to expand prospecting operations into Xen'drik.
Affiliation Score Criteria: Like all Dragonmarked houses, House Tharashk is made up primarily of the race that bears their particular Dragonmark - in this case, humans and half-orcs. House membership is not exclusive to those races, but others are in the minority.
House Tharashk is known for it's dragonshard prospectors, inquisitives and bounty hunters. While it is hard to gain influence for prospecting, particularly big finds do make the leadership of the house take notice.
