Shadow
You know. You were there. Fighting against the Traitor-Clan until your strength all but ran out. Setback after setback. Finally winning. The dwarves and the orks coming. You were there. When a patrol found your only true superior butchered by the pistols of the Emissary. You wiped away all traces of the treachery and silenced those voices stupid enough to think you didn't know they plotted betrayal. As the only Assassin to survive that hellish place, your would be the star rising from the destruction of the traitor clan. Your the story the one to be told. Master Assassin had a great ring to it.
But you remember. You remember the missing papers in his room. You remember staying back, climbing the cliffs of the mountain to watch how the dwarves would deal with the Waargh. You saw the dragon leave. Not fighting them. And you saw that thing fire. You saw her. The shadow in the dark. The human that was too silent by half.
Your Sorcerer was dead. But someone had killed the Emissary afterwards. Someone capable of hiding from both an Eshin Sorcerer and the Emissary's guards. Someone who'd waited until they were fighting to strike, and taken things from the slaughter, in their rush to get away. Someone you couldn't even smell. You know the too quiet human. Heard in the dark. Seen in the light, as she flew down from her Weapon. Now the only question, is this: who do you tell? The Council?
The Emissary had come to meet with Eshin and died. They would need a scapegoat. So do you blame the Dragon, or the human? Or a sneaky dwarven ranger perhaps. The Council's rage would be mighty indeed for such a loss of face. But if you were to say Mors were dead, a final check was in order. So you send your clanmates ahead, with dire warnings should they linger or entertain any thought of betraying you. And you go back. You climb the cliffs again. And for all the dwarves are wily and old foes, there are too many halls, too much mountain, and too few dwarves.
They might stop an ordinary rat. But not an Eshin Assassin. The bundle of caves serve as an easy entrance, and from there, the mountains are yours.
***
You kill no one, and leave no trace of your passage. Not with Runelords about. Not with copters to hunt you. Not with the quiet shadow human that can hunt an Eshin Sorcerer making this her home. Many times you are tempted to find a closer look at the Weapon. But you abstain. You know well how defended your quarters were. All of them. Things were still missing before you managed to blow your way out of the mountain. So you do what the man-thing must have done. You scout. You piece things together. You find the rooms where the Mors breeders used to be. Confirm the kill. And slowly, you plot and plan the tale you will tell the council.
Of the foolishness of Skyre and the wrath of a Dragon. Of hundreds of thousands of Orcs and a tower of fire. Of a newly risen dwarven kind, and a quiet shadow in his wake. How many times, you wonder, did other Clans mistake her work, for one of your kin?
As you sneak back out through the caves and cliffs, you look back to the place that broke so many Skaven Clans and ended Mors.
"Well played, man-thing. Perhaps some day I'll be back to hunt you." After all, there's no one stopping you from reaching greater heights anymore. And while the Council needs to know, what kind of dutiful servant would you be if you did not ascribe some of the failings and victories in your favor. After all, who will gainsay you? They're all dead, and you are on your way to the top.
"Skyre. Skyre will do. They drew the Dragon. This is all their fault." Blame the Dragon for the Emissary's fate. But you will need to tell the Clan Head about the sneaky man-thing. It would be an embarrassment if one of the Clan was caught on a mission in there. Then again, if they are stupid enough to head in there without consulting their elders and paying for the privileged, they deserve to pay the price of their arrogance.
AN: This feels off, especially without the proper Skaven-speak, even with Eshin being arguably the most human of the clans. But I just can't be bothered to look up the proper speaking patterns right now.
Born from the idea that if Eshin was running away, they would have sent scouts sooner or later. And an ambitious one might have thought to stay back and watch the battle, since the Caves had an entry point for climbers, and Eshin Assassins/Clanrats are definitely trained in stealth and climbing.
