I noticed this while farming webs for Nick. I can't find where anyone else has pointed this out, so hopefully I'm not picking out old news.
The Wilds is a Mantle outpost, right? Witness Giselle is there to tell you about the mission and even in her initial dialogue to you she asks you aren't hunting Shining Blade.
Here's the oddity: While there's nothing on Sihor's, the merchant, clothes or body to indicate that he is Shining Blade, both the tent and the banner in his corner bear the Shining Blade insignia. I can post pictures if you like.
Any ideas what those are doing there? Seems odd to have a loyal Mantle of some small standing, and spitting venom about the Shining Blade, would tolerate those insignias being in the outpost.
