PS The first turn has a 48 hour deadline just in case there's any problems, but hopefully it'll go much sooner than that because it shouldn't take people long to do their turns. After that it'll be on 24 hours.
Ha ha ha! The hydras desperately (?) blocking the entrance to the fortress against a much greater force, and succeeds, reminds me so much of Heroes of Might and Magic II. Man I love that game.
