Legendary Item Recipes

Where do the Legendary Item Recipe go when used? I picked up 2 Legendary Recipes on completing Layer 3 of Torghast with my guildies. I know 1 of the other guildie got 2 recipes as well for his Hunter. I hadn’t seen the item before either so kinda thought it was Anima Power just about. Back at the Runecarver, I looked at the Legendary item again and realized it said restore or return Runecarver’s memory. I think it said use on it. So I clicked on it and it ding and then disappeared, but got an achievement. So the question is Where did it go? Where are Legendary Item Recipe stored. If the recipe is also unlocked Account Wide it has to be stored somewhere for other alts to use assuming it’s a class that can use it. So then it has to be stored someplace. Where is it stored?

It is stored under the legendary tab in your adventure guide.

I do not believe the powers are account shared, but I could be wrong.

Just know the UI, or the system is currently bugged/screwed up. Certain legendary powers even after being learned cannot be applied to the items listed.
