"For generations, the Wyyrloks served you, kept you alive, served as your voice when your physical frailties forced you into stasis! We hid your weakness! What do you know of me? Of my own desires and plans? Nothing! I kept my own counsel and waited!"
About this creation
Darth Wyyrlok was a Chagrian Sith Lord during the time of Darth Krayt's One Sith Empire. Wyyrlok (III) was Krayts most trusted servant and he used this to his advantage. After several years Wyyrlok killed Krayt and took the title of Dark Lord of the Sith.
However Krayt was not dead, he returned to Coruscant and, despite Wyyrlok's attempts to convice his fellow Sith that Krayt was an imposter, the former Dark Lord struck down Wyyrlock and reassumed his title.
