The Ghost Raiders' gene-stock is derived from the 1st Founding White Scars chapter. On the most part, purity of the Ghost Raider gene seed is standard of that expected of a White Scar successor Chapter. Regrettably, two Astartes implant organs, namely the Omophagea and the Betcher's Gland, have been found to develop only limited (or non-existent) functionality in Neophytes and Astartes. These slight deviations in the gene-make are closely watched for signs of change or further mutation. However, frequent testing has reiterated the stability in the Chapter's source of gene-seed and it's circulation within recruitment cycles, showing no signs of major degradation or mutation.
