Twilight Fog Brings Madness

Does Flame's Fury boost damage to Dahan?
With Flame's Fury, you must boost one instance of Damage of your choice, either to Invaders or Dahan.
Usually, you will choose to do that Damage to Invaders, but with a power like Twilight Fog Brings Madness, you would have to do extra Damage to Dahan. Note that this is different from Badlands, which separately boosts Damage to Invaders and to Dahan.
With a power like Insatiable Hunger of the Swarm that deals damage to both Dahan and Invaders, you can choose to boost damage to Invaders, even if there are no Invaders in the land.

Must Gather/Push effects which don't say "up to" move exactly that many things? Eg: Does Fields Choked with Growth move exactly 3 Dahan?
Yes, if possible. If a card gives a number of pieces to move, you must move that number if you can, or as many as possible if there aren't enough of those pieces there.
Most "move some Dahan" powers represent the Spirit asking/working with the Dahan or calling in favors. A few, like this one, are more "the Dahan decide to get the heck out of Dodge". This applies to other kinds of pushes, as well.
Other cards with similar wording are Terrifying Chase (Sharp Fangs behind the Leaves), Sacrosanct Wilderness (Keeper of the Forbidden Wilds), and Twilight Fog Brings Madness.
