Son of Agust Eikson of the Eikson Clan. The Eikson Clan has always been famous for their swimmers and their underwater fighting abilities.
Gunter, who is considered the greatest Master of vatten krigare, the ancient Nilfeheim water martial arts, rarely accepted pupils but he immediately traveled to the West to comply with his friend's request. Eric never knew that Gunter Eikson asked him to be his pupil because Egill had arranged for it.
Eric became the last pupil Gunter ever trained. He considered Eric his master achievement and said that once you created a masterpiece you did not need to try again.
