System: Vendrell

Mountain Wolf BattleMechs started up in the 26th century as a light 'Mech manufacturer for the Star League, whose Night Hawk BattleMech successfully competed against Defiance Industries' proposal for a new light strike unit to supplant the Stinger and the Wasp. After the fall of the League, Mountain Wolf continued to produce Night Hawks well into the Succession Wars, though the decay of technology reduced their performance to a mere shadow of their original design specs, until the Vendrell factory was destroyed by Marik forces in 2945.

In 3055, Brandon O'Leary, great-grandson of Eli O'Leary, Mountain Wolf's last President and CEO, invested much of the family estate and drew on a host of corporate and government contacts to reopen the Lyran plant at Monte Lupus, following his success in restoring the company's Alpheratz plant more than four decades earlier. Reintroducing the company’s signature 'Mech has gone a long way toward boosting Mountain Wolf as a major military producer, but despite brisk sales in the wake of the FedCom Civil War and sales of their heavier Merlin to Periphery interests, the company remains in precarious financial shape.
