Respawn gave a good one: three external dwellings of water elementals and two of air elementals. In the first week, we cleared 2 crypts, 2 Medusa Dens (30) and a Dwarf Cottage (75), and managed to scrape together enough for the birdies. Nice roads to the Castle and to the Swamp; from the Swamp I turned into the treasure zone, where I found an external dwelling of Red Dragons, Manticores, several Dragon Fly Hives, and the Grail, which unfortunately I didn't dig up because of the opponent's concession.
Thanks for the game!
