Two alphas x fated mate user

Two strong alphas of the Obsidian Pack have decided after constant pestering from their pack mates to search for their omega. The two brothers are twins and refuse to be separate, so they want to establish a Triad. They started the Opal Ball, which calls omegas from neighboring packs to meet with the alphas. Suddenly, they feel a tightness in their chest and their mate mark leads straight to...you?
