Lux Veritatis
From WikiRaider
The Lux Veritatis ("Light of Truth") were a secret 12th century Order of warrior monks, an offshoot of the Knights Templar. Dedicated to suppressing evil, particularly works of Sorcery and alchemy. Responsible for destroying Eckhardt, the Black Alchemist, in 1445.
They hid the Obscura Paintings in the 1400's.
It is said that they posses the three Periapt Shards, artefacts of power, crystalline shards shaped like spearheads, "weapons of light".
Kurtis' father was the leader of the order, till he and many more were murdered by Eckhardt. Kurtis took over from him, and set out to stop Eckhardt.
The Lux Veritatis is also central to the plot of the fan-created custom games Tomb Raider: Legacy and Tomb Raider: the Angel of Darkness 2
