It went bye bye... the day after it was launched. Supposed to come back in January, but haven't seen any date announced.
But, it was in Shadow Haven, in the basement of Shandling's Roost (or something like that). You bought a token for 100p from a merchant, then you gave it to a class specific guy who would give you something (or nothing) at random (mostly no drop stuff).
Pretty much a plat sink, but since no one is making anyone gamble, I thought it was ok... I spent 200pp, and got a loaf of no drop bread.
