Nephium
From Warhammer 40k - Lexicanum
Nephium is a highly flammable substance that has a myriad of uses in the Imperium. [1]
The most common usage of Nephium is as an additive to Promethium which greatly enhances its quality. Greenish-black and tar-like in appearance, Nephium is highly toxic to organic tissue. Contact between Nephium and unprotected skin usually leads to a prolonged, painful death.[1]
