The Hyena was created as an arena and later battlefield salvage 'Mech by the Vining Engineering and Salvage Team of Solaris VII. The design was originally built from converted Kintaro BattleMechs, and were later offered for sale in 3066. VEST only finished one production run prior to the Word of Blake sacking Solaris VII in 3068. First production units went to various mercenary groups, Great Houses, and even several Periphery nations, including the Rim Collection. VEST sold one Hyena at reduced price to a specialized salvage team, Skibinski's Salvage, in order to showcase their SalvageMech's abilities to various prospective customers through the unit's travels.
In 3072 Word of Blake forces dealt a blow to the Hyena’s sales with the destruction of VEST's production facilities in the city of Xolara. Sales of other SalvageMechs such as the Jabberwocky began to lure potential buyers away. [Source: sarna]
