When I was doing my botany leve the other day that is badly placed in the field of Kobolds I was thinking how cool it would be for the volcano to erupt and flow down that valley area towards the Kobolds. You don't have to eliminate Kobolds from the game, they can run to safety near Bald Knoll or whatever. But I'd love to see cool stuff like that happen in the game.

The volcano probably wouldn't threaten Limsa itself, it's so far away. An ash weather effect would work well however.
