Editing Gemini Legion (section)

===Gene-seed Flaws===
Whether brought about by their mental conditioning, a modification to the Red Thirst, or both, Marines of the Gemini Legion suffer from a deep codependency; a Marine that loses his partner in battle will succumb to a blood-thirsty rage from which he may never return.

Another peculiar flaw in the Gemini Legion is the growth of a second head. While there are no apparent deficiencies or benefits in battle, those to grow another head are said to be more receptive to other brothers, and as such, more likely to promotion. Their Gene-seed also leads to much more aesthetically appealing Astartes, which leads them to have a strong alliance with the Pretty Marines, and an absolute abhorrence to the legions of Nurgle.
