This is a small bundle for the latest Hyperborea 3E RPG (née Astonishing Swordsmen and Sorcerers of Hyperborea).

For $13 you get

Hyperborea 3E v1: Player's Manual ($12, currently $9 on sale)
Hyperborea 3E v2: Referee's Manual ($12, currently $9 on sale)
Atlas of Hyperborea ($5, currently $3.75 on sale) - 40 pages
The Late Trapper's Lament ($10, currently $7.50 on sale) - 1st and 2nd level adventure
Hyperborea Referee Screen ($10, currently $7.50 on sale, already own) - this is the 2E screen, though I guess fully compatible with 3E

For me it's $28 worth of material so a good discount.
