Swamped

Smoke.

You don't know where it came from, or what caused it. Just to be sure, you check your mistflower pouch, but it's still securely sealed. And your mistflowers wouldn't be this dirty, anyhow.

Whatever the cause, it's not far off, and it seems to be drifting your way. If the smoke reaches your hole, that's likely to draw unwanted attention. What's more, with how thick it is, you're not sure your suit's filters can keep it all out.

You decide that you'd better investigate, so you start following the smoke to its source.

It looks like a campfire. A lit campfire, beneath the fortress floors, with water all around it.

Bizarre as the sight is, it's even moreso when you consider that you've been down this route before. But considering your own presence, and that of the bees, you have a guess at where it came from: the desert.

Although, why would anyone need to light a fire in the desert? It's hot enough there already. You wouldn't risk it unless it was dark, and it shouldn't be dark there now...

Well, that can wait. You start splashing water on the flames to put them out.

Except, nothing is happening, no matter how much you douse the pile. How can this be?

Wait. There's one way you can think of. You take a closer look at the firewood.

Sure enough, there's a small stick of darkwood in the center. Someone's set darkwood ablaze. But why?

Well, that's a question that can wait. For now, what matters is dousing it. Unfortunately, that won't be simple; once darkwood starts burning, it's hard to stop it, and you don't have a lot of resources on hand.

So what are you going to do about this?
