We think it is possible to use a wind stone to ambush a duke of the Abyssal Council. To do this, however, one must commune through the wind stone, and convince the council you are a middle ranked leader of the Twilight's Hammer.
Such a gambit requires a replica of the cult's medallion of station. I can create the medallion, but I will need a large brilliant shard, and crests worn by the Abyssal Templar.
Ah, very good. I've been working on the medallion - now with these last ingredients, I'll be done in just a few moments...
There we are. Here is the medallion, <name>.
You'll need to wear this when you activate one of the Twilight's Hammer's wind stones. Put this on, along with the rest of the twilight trappings, and the Abyssal Council will see you as one of their cultist underlings.
