|Elim, Lime and Zaid|
Iris is an NPC.
Iris is located by the Tower of Training in Elim, Lime and Zaid. To find her you must get access to the warp by speaking with D.End, who guards it. You need to be level 20 to gain entry to the warp and Iris. By doing so, you can begin the quest: The Trail of Heroes Quest.
By the story goes, it is revealed that Iris is the daughter of Vivi and Tristan. She is Half Elim-Balie, a mixture between Vinagh and Sakiel altogether and the first human to have the blood of Elim and Balie's succesor.
