Grenden is a member of the old Blackthorne family of Eleusis. His mother Shandara sister Ishka, and himself led a crime ring around Eleusis and the Eastern Ithmia, in the year 363AF, under orders from a mysterious woman called Felisse, of the Jaguars crime ring. Shandara and Iskha were murdered at the gates of Eleusis, while Grenden was spared.
Grenden took up citizenship in Eleusis, watching over their fields for many years.
He often complained of being bored, so Aztecia sent him on a quest to study elementalism, to help her summon an elemental spirit that was to become a Eleusian loyal. Upon his return the ritual was complete, and Ellie, the elemental cloud was formed, and became an inhabitant of the forestal village.
After spending many more years practicing his new found skills in the ways of the magi, Grenden approached Urk'thal, the Blademaster of Aegis, to retrain him in the ways of the blade. They spent many years in the training hall in the temple of War, before Grenden took up his residence in the barracks of Eleusis, where he can still be found today with his loyal black fox.
