Jarel-karn cuts down a tapestry from the wall. He then roll the sword in the tapestry, never touching the sword directly, and tie it down.
"Yes, this sword was holding an ancient magic. An avatar who spoke in the name of the Council of Ravens, whatever it is, had taken possession of your commander will. Vahl had, under the influence of the sword, had cursed the lizardmen first, and then the poor quarter. When we confronted her, we had to fight. As we had subdued her, the Avatar took over Vahl body, knowing we were aware of the nature of the sword. The avatar couldn't accept the defeat. She raised into undead Vahl's personal guards and try to finish us. That's when you arrived.
I am well aware that attacking Vahl and her guards was a crime, and I am ready to answer to it. But I will defend myself and will need to reveal what act Commander Vahl have done under the power of the sword, and darken her reputation.
I suggest what happen here stay here and that Vahl felt into combat against the old god to save the city and the lizardmen. That her sacrifice will become the stone on which a new lasting peace will be build between your city and the lizardfolk. A symbol your poor would be proud as she had defended them against a power greater than anyone in this city.
And for the sword, it's magic is weak. I think we could put it into a powerful fire, like one in a forge, and melt the sword down, releasing harmlessly the remaining magic within it. I woudl like a second opinion on that matter, by my friend Yishim will be able to give it. If you have any arcane expert, a third opinion would just be welcome. We donèt want the avatar to come back."
