Shirion may have been a human once. That time is long past. Now, it is an ever-shifting being, its form lost to time.
Brendan stared at the creature in the pale moonlight, transfixed by the silvery petals that glistened beneath that perfect purity. It was not until his final breath that he gathered his wits enough to scream after the thing had descended on him, all muscle and thorns and hard, barklike skin. It was too impossible, even the crimson blossoms that shone in the light of the moon.
These small, luminescent creatures are a distant relative of the willowisp, little bits of orangish light that are attracted by the flames of a fire. When enough of them have gathered around a fire, the fire appears to take on a fuzzy indistinctness.
On a world made entirely of molten rock, there is still life.
The PCs are making their way from village to village across a rural hinterland, when they spot a weird sign along a farmstead's fence, with an arrow pointing to the actual farmstead.
"CRAZY DANCING HOES!!"
If they investigate, a rather sedate local farmer, explains to them that for a mere two coppers, they can witness the show for themselves.
The show involves six ordinary, animated hoes "dancing" on a makeshift stage, as the farmer accompanies them by slapping his thighs to keep the beat, and playing on his flute.
If asked how the trick is accomplished the farmer demurs, not wanting to share his "secret".
"If you can get Old Man Purkiss to tell you how he gets his cows to spout poetry, I'll tell you how I make my hoes dance."
In reality, this minor encounter can lead to the PCs discovering that some localized, magical effect is active in the area. All kinds weird phenomena seem to occur in these parts.
Perhaps the PCs have finally found the ley-line of mana energy that they have been searching for! The party's wizard gets excited.
