Naorstrachem

Naorstrachem was a highly flexible substance, which was often used in the creation of netting or webbing. Synthetic Naorstrachem was used by Merr-Sonn to fabricate the webbing that was shot from the Anti-riot tangle gun 7. The synthetic form was often combined more readily with a shrinking agent, which was required for not only contraction of the webbing around the target, but also ease of storage within a gun.
