Seth Sorenson

Seth Sorenson is Kendra's younger brother, 11, and has a much more out-going, risky, curious, and adventurous personality. Seth has great courage, but little patience, and he does not always think things through. Because of this, he tends to be the source of mischief as the story continues. In book 1, Seth gets turned into a mutant walrus because he turned a fairy into an imp unintentionally by holding her captive overnight. The family then has to go to Muriel the witch to change him back, and as a consequence one of the knots that binds the witch is lost. Against orders, Seth opens the window on Midsummer's Eve allowing goblins and other creatures into the house. These creatures kidnapped Lena and Grandpa Sorensen and also turned Dale into a statue. This left Seth and Kendra alone to find a way of rescuing them. They later have the help of Grandma Sorensen, after they loose Muriel's last knot in order to free Grandma from her altered state. Seth doesn't play a major role in the rescuing of the preserve.

In book 2, Seth goes into a funeral home and gets bit by a statue of Olloch the Glutton causing the demon to awake and eventually grow strong enough and big enough to pursue Seth in order to eat him. Olloch devours him eventually but he survived in an impervious fairy cocoon given to him by Coulter. Seth takes a powerful courage potion and confronts the Revenant. He is successful in removing the cursed nail from the Revenant, defeating it. This allowed Kendra and Warren to pass through the revenant's territory and enter the tower. In the confrontation, Seth becomes immune to magical fear that some dark beings radiate. He also gained the ability to see some elements of darkness that are hidden to others.

Seth visits the demon Graulus who appears in the third book and learns that Navarog, the dragon prince, was the one released from the Quiet Box, and that he retrieved the talismanic nail Seth had removed from the Revenant, and gave it to the demon Kurisock. Meanwhile, in Lost Mesa, Kendra finds the key to another hidden preserve. Seth successfully retrieves the Chronometer and inadvertently brings Patton Burgess to the present time. Seth, Kendra and Patton then face the final battle to defeat the Shadow Plague.

Seth gets into more trouble by stealing the first horn of a unicorn from the centaurs, their most prized possession (aka the soul of Grunhold/Ring of Stones). He finds out he is a Shadow Charmer, and many are not sure if they should trust him because Shadow Charmers are usually the villains. He is then denied from the group journeying to the dragon sanctuary Wyrmroost because of his age, (and his possible dark attributes) but that won't stop him from going. Seth sneaks into the knapsack that his sister received that holds an extra dimension. He makes friends with a giant and other creatures of the night. While at Wyrmroost Seth and his sister Kendra find out that together they could be a dragon tamer. They together slay Siletta, a poisonous salamander-like dragon, whose entire body consists of deadly poison, and many other monsters. Even after Wyrmroost, Seth is still able to laugh.

Seth heals the demon Graulas, who steals two of the artifacts from him. Graulas kills Coulter in securing the third artifact allowing Graulas and the demon Nagi Luna to open the great demon prison Zzyzx. Seth releases the narcoblix Vanessa. Meanwhile, Kendra and Warren join forces with the Sphinx. The prison is opened and all of the demons are released. Seth kills Graulas and Nagi Luna single-handedly. Unlike his sister, who knew about traitors in particular, Seth learns a lot about the evil nature of demons.
