I have the Quest "Discovery of a New Technology" to craft a Ancient Weapon Codex. What do I get, where do I get it in order to craft this. Returning player so clueless.

OK, thanks but I don't know where that may have come from. Combined, my toons don't have that much or have sold any thing like that. I'm making alts to get stigmas. Appreciate your reply.

I have played since launch, left 2014 and am returning player. I have not encountered this before. Is there a selling limit? If so, why get a prestige pass? This happened yesterday so will it reset. It said for the week. The forum doesn't connect to current player info. I posted this. Name KallaSiel, 80 Chanter.
