 Unique Dialogue
"You are Argonian, yes, but you are no Shadowscale! What chaos you must have known as a hatchling! Thank Sithis you have come home at last. Welcome."
"Ocheeva and I have know Lucien since we were hatchlings. He is the one who trained us in the way of the Shadowscale, and is like a father to us."
"In the Argonian home land of the Black Marsh, those born under the sign of the Shadow are taken at birth and presented to the Dark Brotherhood. A Shadowscale hatchling trained in the arts of stealth and assassination, and lives a life in service to the mighty kingdom of Argonia. Any Shadowscale who lives to come of age is accepted into the Dark Brotherhood as a full member of the family. So it was with myself, and Ocheeva."
"Ah, dear friend. May I steal a moment of your time? I have a rather delicate situation I was hoping you could help me with. This is a personal matter, and will have no bearing on your standing withing the Dark Brotherhood. Would you like to hear more? I find your decision most agreeable! Now, the details. Far south of here, on the southern end of Cyrodiil, lies a swamp called Bogwater. Hiding in that swamp, you will find an Argonian Shadowscale named Scar-Tail. Kill this renegade, and bring me his heart as proof of the deed."
"When Ocheeva and I trained with the Dark Brotherhood as chidren, we befriended another initiate, a Shadowscale by the name of Scar-Tail. The three of us were inseperable. When our training was complete we reluctantly parted ways. But now... the unthinkable has happened. Scar-Tail has fled Black Marsh and refuses to fulfill his duties as an assassin! This is an act of treason! This treachery must be punished! Just as a member of the Dark Brotherhood, cannot kill a family member, a Shadowscale is forbidden from slaying another Shadowscale. That is why you must go to Bogwater and eliminate that treacherous snake! Please kill Scar-Tail, so Ocheeva and I can put this matter behind us."
