NPC: A dancing spark
Long Desc: A spark dances here in the darkness.

Twirling and leaping from place to place is a small, animated flame.
Brought to life through magic, it has no face or features.  You have a
feeling that it knows you're there, as though you are being scrutinized by
this column of light and heat.  It seems to be some kind of fire elemental,
except in a less evolved form.
It is a elemental approximately 7'0" tall.

This NPC can be found in: Sigil Underground.
