Has B10 been erased from the history books. It isn't available as a .pdf, and under B11 there is this line:"Expanding the Known World. "King's Festival" was just the second Basic adventure strongly placed in the Known World, the other being B6: "The Veiled Society" (1984)."Of course, perhaps B10 is classified as a basic/expert adventure, but it is still a strange line (and absence from the store).
Rumour has it that B10 will appear half February.
