okay,i was searching the web to see if i could maybe find a premade adventure and i found people who said there are adventures(though,judging from the dates they were probly meant for the d20 version)
The first link says there is a published adventure...

And the second says FFG had a preview adventure...

Does anyone know where i can find them or if they even exist
