<name>, we are going to need a high quality cloth to work with. Thankfully, the weaving quality of nightborne craftspeople from long ago was very good. It is a lost art to some degree but I feel like you can take their masterworks and do even more with it.
Some of the hostiles in these parts still wear Ancient Imbued Silkweave Armor. Start to unstitch the silkweave cloth from any of that armor that you find on Broken Shore.
