"Lo there do I see my ancestors, faces cavernous with rictus grins
Lo there do I see my woman, her womb torn asunder and fetus thus removed
Lo there do I see my Santir, head upon the Amarrian spike
Lo there do I see all those who have gone before me and those who will come after me
Lo do they say that I have wrought all of these images for I was not diligent against the beasts
Lo do they strip me of name, of tribe, of standing and self
Lo do they send me forth to claim that which was stripped from me
Lo do I wrest what was stolen from me from the Amarr
Lo do I take their lifes blood, do I carve flesh from bone
Lo there do I see their faces now cavernous with rictus horror
Lo there do I see their women, wombs asunder and fetus thus removed
Lo their do I see their Holders, Head upon Matari spikes
Lo there do I see my body dying, their revenge upon me as mine is upon them
Lo there does our world darken to me as lifes last breath doest leave me
Lo there do I see my ancestors awaiting me
Lo do they say to me, You are Los Muertas No more"
Los Muertas is not a name but rather a title taken by a Murientor or Thukkar. The Los Muertas are Matari whom have seen their entire way of life stripped from them and, in their own mind or by reality, could have done something to prevent a cataclysm from falling upon their Clan or Tribe. Los Muertas itself means plainly "Lost in Shadows" much like a wraith stuck between the shadow realm and reality. They are angry and vengeful creatures set purely on inflicting as much misery and death upon the source of said cataclysm until they themselves find passage into the afterlife.
It is belived that the Los Muertas were the basis of the Valklears, criminals given a chance at redeption (though the Murientor and Thukkar Los Muertas chose this path for themselves without pressure from others). Only through the act of serving their dead, or in the case of the Valklears the Republic, can their sins be erased and their names be restored. However unlike Valklears, Los Muertas will never return to a normal life, death is their only reprieve.
