whats a 'Talespun Memory' (festival of the heroes) ??

I only know of this item's existence through the festival exchange merchant who says you can trade one for two golden tokens
I've searched the entire talespun citadel over and over again somebody please tell me what talespun memories are and where they come from

 

you play the dang minigame

 

It's the reward you get after finishing the main minigame in the event area. Take the airship on the upper deck of detlas to get there if you haven't already (Aster will also tell you about it as well).

You get more of them depending on how well you perform in the minigame, with player win/hero loss yielding base 5, player loss yielding base 2 and hero win yielding base 8 (I think). You can also get bonus ones if you get the most of something in the game (such as most mob kills).

Besides being used to get golden tokens, you can use them directly to get various unique trinkets within the minigame lobby area as well as several different armor pieces (eleventh hour is a really interesting chestplate, I'd save up for it if you can).
