However, the number of Novas has been diminishing. Only spare parts have been in production since 2921. Designed as an early OmniMech by Clan Hell's Horses, the Nova was produced at the famous Tokasha Mechworks beginning in 2870. At the time of its introduction, the Nova was designed for infantry support, and was the first OmniMech designed with hardpoints allowing Elementals to easily mount and dismount the chassis. However, after Tokasha was taken by Clan Ghost Bear during the Battle of Tokasha, production of the Nova ceased. Since 2921, every Clan has acquired Nova OmniMechs as isorla. [Source: sarna]
