Thendrite
From Warhammer 40k - Lexicanum
Thendrite is a rare crystalline material mined from veins below ground.[1]
The Kin of the Leagues of Votann have been known to violently seize sites where this material is discovered. An example would be when the Farsail of Thryk Kindred conquered a mining commune on the feudal world of Ghorrad.[1]
