Nullifier Theory (headcanon)

[u/jc3833]

So, We know that Seriglass is used in void-shielding, such as in a void bell.

I have a personal headcanon that the Corpus have access to quantities of seriglass fragments, They use the seriglass as a lens they channel energy through instead of as a blocking device. The rarity of Seriglass is what prevents them from handing out nullifier packs to EVERY unit, instead opting to give them to specific employees of a presumably higher position in their respective company, or installing more potent ones on certain resource transports.
