Betcher's Gland

The Betcher's Gland is one of the 19 organs that are implanted into a Space Marine inductee to produce a Battle Brother. Implanted into multiple locations inside a Marine's mouth, these glands transform a Marine's saliva into corrosive, blinding acid when triggered. This allows a Space Marine to spit a wad of corrosive acid with the effect of blinding wounding or even killing an enemy. Its more common use is to aid in the digestion of usually difficult or impossible things to digest, such as cellulose. In the geneseeds of several primarchs, such as Rogal Dorn, this organ has atrophied and is no longer as effective.
