"𝓚𝓪𝓵𝓭𝓪𝓽𝓱𝓲 𝓝𝓮𝓿𝓮𝓻 𝓓𝓲𝓮."- Warcry of the Ghost Stars
Sarthas Navahk is an immensely powerful human Fallen Blade and Death Knight, an undead warlord who seeks vengeance against the Veritas. His innate mastery of the Fifth Force, specifically its darker aspects, is what makes him dangerous to practically all who stand in his way. He learned such ways through his shared exile with the Kaldathi following the Great Interstellar War.
His Death Knight name following his resurrection is Cyndrak.
During the Great Interstellar War, Veritas justicars fought in mass combat with the Kaldathi using the deadly Vis blades. Some left the Veritas Order altogether, only to be cut down later by their former brothers and sisters. Many of their corpses were not recovered, and instead were resurrected by Yjormun the Immortal as undead thralls. These Death Knights were used as shock troops, bound in heavy void armor and sent into battle with Vis blades and their own personal usage of the Fifth Force.
They were functionally immortal, having been bound to their armors by powerful Kaldathi sorcery and the power of the Fifth Force in question. Such was the refined majesty of the Kaldathi rune-magics that the Death Knights often outlived their lords and masters, instead becoming roaming warriors. Only a few survived into the end of the Great Interstellar War, and were exiled alongside their remaining Kaldathi and Fallen Blade lords. When they emerged following the rise of Chorona Valman, so too did their Death Knights.
Cyndrak is one such wanderer, having long ago sworn an oath to never die until the Kaldathi became supreme once again.
