Dorvalla Mining, a member of the Commerce Guild, functioned as a corporation that mined lommite. It held dominion over the planet Dorvalla and managed both the Dorvalla Penal system and the Dorvalla Space Corps.
Following a period where both Lommite Limited and InterGalactic Ore hired the Toom clan to disrupt the other's shipments, Dorvalla Mining was established through the merger of these competing entities. The Toom clan successfully completed both sabotage contracts, which significantly impacted each company, thereby compelling their unification into a single organization.
