My 3rd entry for the colossus contest:
"The avatar of the red one"
Meaning the red dragon, who is the leading power behind all fire plane creatures.
This one was hard, I spent a long time on the design. At first I wanted to paint a dragon, but Dragons are always special in rpgs. In Rift there are the big dragons, each controlling one element. Of course the red one is for fire.
Next idea was some vulcano, mountain monster... look through the entrys so far and you will find lots of examples.
The final idea came from the sun and some pictures of venecian masks. Et voila!
The two sun rings are rotating and after some time a fireball will appear in the outer ring. Then a 2nd and so on, untill the ring is complete. That is the timelimit for the raid, when it is reached a bright lightball will appear on the dragon's nose, starting to shoot a laser like firebeam. Killing all raid members.
