Barbara Sennet began her career as a Star Captain with the 222nd Striker Cluster. Earning her Bloodname at age 25, Barbara went on to command Gamma Galaxy at 29 and Beta Galaxy at 35. Her career has included victories over the Star Adders, Smoke Jaguars, Cloud Cobras and Ice Hellions. Her last victory as Beta Galaxy commander also resulted her in being elected to saKhan after her predecessor, saKhan Jordan Clarke, was killed in action. Though she harbored reserverations about Khan Hawker's opinions about freeborns, his recent policy changes have made her life easier. The influx of qualified freeborn MechWarriors, fighter pilots, and Elementals has greatly alleviated her staffing concerns as she rebuilds the touman.

Khan Sennet faces the daunting challenge of rebuilding three full Galaxies from scratch. The near total destruction of Alpha, Gamma and Omega Galaxies at Tukayyid has placed formidable burdens on the saKhan. The allowance of freeborn warriors into frontline Clusters and new Omnimechs obtained from Clans Jade Falcon, Nova Cat, Steel Viper and Wolf have given the Diamond Sharks an enormous lift as its factories rushed to replace the lost materiel. These coupled with the strategies devised by the various Star Colonels have added a whole new dimension to the Diamond Sharks future.
