Still, it might be hard unless she has a lot of paper.

Lise doesn't have anything that could fuel it. Not that she would want too.

She used all the paper to set the place ablaze. She made trails towards anything flammable, such as paper artwork or wood.

No artwork here, but plenty of wood.

Lise turned away, clearly uncomfortable. It wouldn't be long until someone smelled smoke.

That should keep it going. In the meanwhile, she scoops up some of the soot being made, two handfuls worth, and hands one handful to Lise. "Smear it all over yourself. People will notice quite quickly the place is on fire. And leave the alibi to me and do not say anything about it unless you're agreeing with me."

She takes it from her. " Fine. " Then smeers it on herself.

The fire is climbing a tree quickly

She sits down. "Act traumatized. We've just come out of a burning building, a heavy log fell on the satyr and she's trapped inside. You saw some smoldering plants nearby, but presumed they'd be put out. They weren't." This is presumably the aforementioned alibi.
