I can't remember the name. I know they were doing a sealed auction for these dice (they said they were going to launch a Kickstarter for them sometime soon), they were the biggest set of 7 dice I had ever seen. I believe they were resin and the booth had a lot of other dice being auctioned off too. Any help would be appreciated! To my recollection they were somewhere close to the 100 aisle of the exhibition hall.
I am pretty sure it was Roll for Initiative. There was a problem with their recent Kickstarter and they wanted to raise some extra funds to recoup costs incurred from extra shipping.
