Darth Vilus's writings
The writings of Darth Vilus, a Sith Lord, numbered over three thousand separate books during his lifetime. Darth Thanaton possessed the original set of these writings, which he kept within his private library located on Dromund Kaas. Thanaton tampered with the publicly available version, substituting volume 2,397 with a copy of volume 2,455. Lord Kallig, upon discovering this act of forgery, was compelled to infiltrate Thanaton's library to gain access to the authentic writings.
