As mentioned in this thread
every game pre-ordered or bought at the fair in Essen (13 - 16 Oct 2016) comes along with a tiny give-away (as long as stock lasts).
The small package contains the "Stones Of Fate", two nice acrylic stones (black for the Fomori and amber for the tribes).
During the game (either permanently or at the end of each round), players are able to keep track of the amount of locations occupied by the Fomori and by the tribes respectively.
For this purpose, the stones are laid next to the Fame Point Track, indicating the respective amount (e.g. if Balor/Fomori occupy 17 locations, the black stone is put next to the number 17 of the Fame Point Track).
