While lost in a foggy forest, the party comes across an elf in a clearing. This elf is acting very strangely; before it takes a step it puts down a plank to step on, then picks up the plank behind it and repeats this between the two planks.
The party knows the forest is dangerous, so they try to speed the elf up, until eventually they wrestle the planks away from the elf in hopes that she will begin moving normally, and break them in two. Instead of moving more quickly though, the elf collapses sobbing and crying on the ground, refusing to budge at all. They party had somewhere to be, so they hurried on after it became appearent that the elf won't move from that spot.
As they wander lost in the fog, they come across another clearing, very similar to the one before. In this clearing, they find a very emanciated female elf, dead. Her legs broken.
