Dungeon Lords: Festival Season is a big expansion that includes lots of Dungeon Lording goodness.
The game is still played over two years, but now each year has five rounds instead of four: winter, spring, summer, autumn and festival season. More time to build your dungeon, but also more time for adventurers to gather a larger party. There are new monsters, rooms, and traps to prepare your dungeon for the battle, but also new nasty spells for the adventurers and sneaky bards who encourage them to perform so-called "heroic" deeds - not to mention two paladins for each year, now ready to punish up to two evil players.

Also, your minions get new options - there are still eight actions on the main board, but each round, one of them is replaced by a unique opportunity. Would you like to push other players toward evil instead of moving yourself toward good when visiting the city? How about making an investment instead of traditional gold digging? Or how about repairing conquered tunnels or rooms instead of digging new ones? Take advantage of these special actions while you can; each one is available for only one round. And did we mention that it has recently become fashionable for Dungeon Lords to have their own personal pets?

And if you still don't have quite everything you need at the end of the year, you can pick up something extra at the Festival!
