Karen is a female Human and the younger sister of Maren Taverndatter. She has worked under her older sister much of her life, helping to run their family inn in the village of Pinewood after their father's death when they were young. A little while before the events of the main comic she annoyed Maren's new boyfriend Trace, who also happened to be the current Grand Templar, so much that he cursed her to grow a pair of Keidran ears permanently. The curse that Trace placed upon Karen as a means of punishment seems to have backfired because Karen actually loves her new ears.

After a raid by the Border Wolf Tribe Keidran on her hometown Karen was forced to flee with Maren and their friends Red and Raine. Currently her plans are not exactly clear however she seems to want to follow her sister and many others of the main cast to the hidden village of Lyn'Knol to finally live in peace again.
