The door to the realm is very hard to breathe by

"The poison realm is dangerous!"

The ghost, or Haunter bit Viper. Her scales heated up to burning tempurature, and the ghost flinched away

It flashes again. it leads down to the last door that leads to something (It is not one of the 4)

*follows it*

It leads to the poison realm

A small dragonet scampers past

*steps inside looking around*

Two figures are visible in the shadows, one large, one small. The large one attacks the small one, but you can see that the small one is fighting back. Suddenly you realize what the flashes were. The small one had purple lights that were flashing.
