"If thou shalt swear by the covenant, to become A shadow of Father Gwyn and Sister Gwynevere, A blade that shall hunt the foes of our Lords; Then I place thee under the aegis, and the power, of the Darkmoon."
Met in Anor Londo, dwelling alone at the top of the Prison Tower that rises high above the Church of Yorshka. It can be accessed from the rotating elevator located after the Darkmoon Tomb in Anor Londo. The tower can be reached regardless of the position of the elevator.
The tower will be visible in the distance. Make a step of faith onto open air to reveal an invisible bridge that leads to it.
She is a tall and skinny woman, with pale skin and blue eyes. She has dark green hair and scale-like markings around her eyes. She wears a veil over her hair and wears a white dress. She is barefoot and appears to have a tail not unlike that of a dragon.
Yorshka talks in an older form of English, and lives in a tower secluded from the rest of Anor Londo. Because of her seclusion, she has little knowledge of the outside world.
Yorshka is first met at the top of remote tower near Anor Londo, which is the highest steeple of the Church of Yorshka. She was imprisoned here by Pontiff Sulyvahn, after he proclaimed himself Pontiff and took control of Irithyll.
Yorshka states that she is the daughter of Gwyn, Lord of Cinder and younger sister of Dark Sun Gwyndolin. When Gwyndolin became ill, leadership of the Darkmoon Blades passed to Yorshka. Gwyndolin gave Yorshka her name, along with her chime.
Yorshka's last memory concerning her brother is him being struck by illness, after which she was imprisoned by the Pontiff's knights. Yorshka is unaware of his gruesome fate. Pontiff imprisoned Gwyndolin in Anor Londo's old cathedral, so he could be fed to the devourer
"Name thyself, stranger. I am Yorshka, Captain of the Darkmoon Knights. What beckoned thee to such a place?"
"Perform Darkmoon Loyalty"
"Thou think'st to- Very well. Captain to this knightless company, I remain. I will grant thee purpose. Thou'st journeyed far; hear my voice. If thou shalt swear by the Covenant, to become A shadow of Father Gwyn and Sister Gwynevere, A blade that shall hunt the foes of our lords; Then I place thee under the aegis, and the power, of the Darkmoon. Thou'rt now a Blade of the Darkmoon. The only knight of our company.
Swear this oath, and face thy solemn duty."
"May the Darkmoon watch over thee."
Kneeling before her
"Oh, good Blade of the Darkmoon, welcome home. If I can provide thee succour, only tell me how."
"Long ago, our father Gwyn, lamenting the waning of the fire, became cinder of his own will. Now, the fire is linked by the champions who have come in his stead. Such is the will of father, and the gods. And so the Darkmoon knights took arms, to watch over those who link the fire. But long ago, our company lost its last proper knight. Only its covenant was preserved, to this day, until the time of thy visit. Heirdom taketh many forms, indeed."
"May I pose thee a question? This tower, this prison, stands tall and solitary, the contraption bridging its lower reaches long unmoving. So... by what path didst thou here ascend? Art thou a creature of the air, or other winged thing?"
"Yes, I can fly."
"Oh, my! I imagined it might be so. Then thou'rt a dragon, or perhaps a crow? Well, whatever thou beest, thou'rt wondrous strange, yet strangely familiar, visitor."
"No, I can't fly."
"No I suppose not."
"Of course not. Think no more of my asking."
"I'm ashamed to say, I know not much of anything..."
Reaching covenant Rank 1
"My Blade of the Darkmoon, thy deeds merit great worship. As captain, 'tis my duty to honour knights of great accomplishment. Please, it is thine, and not lightly given. As a shade of Father Gwyn and Sister Gwynevere, Persevere in thy knightly duty, hunting down the gods' would-be foes."
Reaching covenant Rank 2
"My Blade of the Darkmoon, thy deeds merit great worship. As captain, 'tis my duty to honour knights of great accomplishment. This is a wonder of the Darkmoon, inherited from my brother for this very purpose. Please, take this. Thou'rt most deserving of it. As a shade of Father Gwyn and Sister Gwynevere, Persevere in thy knightly duty, hunting down the gods' would-be foes."
Talking after reaching covenant Rank 2
"The Darkmoon Knights were once led by my elder brother, the Dark Sun Gwyndolin. But he was stricken by illness, and leadership of the knights fell to me. Then Sulyvahn wrongfully proclaimed himself Pontiff, and took me prisoner. Oh where could my dear brother be? If only he were here, I would be most pleased for ye both to meet. As, most assuredly, would he."
Talking if the player has not obtained the "Darkmoon Loyalty" gesture
"Thou think'st to remain? This tower is a prison. Thy presence shall invoke the ire of the tyrant, Sulyvahn. I bid thee leave, anon."
