Tactical Marine

Iin this scenario, you're a Primaris Lieutenant, you can pick any name for your Chapter. You were ordered to address a personnel shortage flowing a humiliating defeat at the hands of the alien species known as "the Kroot." To make matters worse, your Chapter was sanctioned by the Inquisition, and your access to gene-seed, which is necessary to make new Space Marines, was restricted.  In what seemed  like good fortune, you were contacted a rogue Magos Biologis who offered to grow and implant the biological augmentation necessary to create new Space Marines, and at a price almost too good to be true. You pray to the emperor and seal the deal, providing the Magos with a laboratory in your chapter's battle-barge for his work. When the new recruits start to file in a few years later, all looks well, except for one of the new Marines... Something is off about them... Could they be... a female?!?!
