While this is a bit of a spoiler, I got this piece from  ebonyleopard at Anthrocon, and pictured here are two of the Talwyn Masters battling each other for unknown reasons.

Featured left is Lauren Rivers, the Talwyn Master of Water, capable of commanding and generating water in any form she wishes. A generally gentle person, she prefers to use her powers in a nonlethal fashion if at all possible, though she has been known to use columns of water to crush large metal objects.

Featured right is Isabelle Sheridan, one of the first Talwyn Masters to be revealed in episode 1. She is a female arctic vixen, commanding the element of ice. She can freeze objects and create anything she wishes from ice.

The scene depicted is from the series third or fourth season, in which case the twelve Talwyn masters have come to a disagreement as to their future course of action, and have decided to settle their dispute with magic powers. :)
