TitleLord of Illusion
He is gloomy and reticent, and symbolized by illusion, fear, and the Spiritmaster class.
Kaisinel's first appearance is at the start of the 3.0 campaign, where he orders the (Elyos) player to go to Sarpan and assist Kahrun in an attempt to keep him away from Siel's Relics. During this meeting he is shrouded in a blinding light, and the player thus only hears his voice. He later appears in person during the fight against Tiamat, in which he saves the player and then proceeds to slay the Dragon Lord while in his Divine form.
Throughout Aion 4.0-4.7 Kaisinel could be seen and freely talked to in-game in the secret chamber in the back of Kaisinel's Beacon in Katalam.
In the 4.9 campaign the player meets Kaisinel again (or for the first time, if they started Aion after the events of 4.8). This time he is residing in a special realm in which he is slowly recovering his energy after the events of the Upheaval.
Ariel, while asking her subordinate how is the fight is going in Tiamaranta, reveals that Kaisinel is the commander of the Sanctum Expeditionary Force and that his task is to destroy Tiamat. However, according to Vaizel's reports, he is having a difficult time not just because of the Balaur, but also because of the Asmodians and Marchutan.
Kaisinel appears in person in the battle against Tiamat. He saves the player because they refused to yield to the Dragon Lord even in the face of death, after which he turns his attention to Tiamat herself. After the player neutralizes Tiamat's control over Siel's Relics the Dragon Lord becomes weakened, allowing Kaisinel to overpower her and ultimately slay her with his special attack.
After the destruction of Israphel and Siel's Relics Kaisinel turns his eyes to Katalam, which had just come under attack from Dragon Lord Beritra's forces. In order to lure out Beritra and discovers his intentions he takes the player, who is currently unconscious from the aftermath of an Asmodian attack, and puts them in a state of suspended animation for six months. During this time Kaisinel and his agents reprogram the player's brain with magic, making him/her very gullible and agreeable which should serve as the perfect bait for Beritra. After this plan failed the player confronts Kaisinel, but the Lord refuses to lift the magic or even apologize.
It is revealed that Kaisinel went missing during the Upheaval. A sidequest reveals that the Lord is still alive, but "probably overexerted himself" during the catastrophe, and is now biding his time somewhere while he recovers.
Kaisinel issues a summons for the player, who thus travels to the realm in which he now resides. This time however his personality is in stark contrast with before as he actually acknowledges the player's efforts and skills. He gives the player his personal seal, making him/her the temporary commander of his personal Kaisinel's Wings Legion, and orders them to lead the charge against Beritra in the Drakenspire Depths. After hearing of the player's prowess in battle and the way he/she honored Killios' memory and sacrifice, Kaisinal expresses his gratitude to the player for the first time, even offering them to take up Killios' now-vacant spot in his personal legion.In the aftermath of these events, one of Kaisinel's agents remarks that this was the first time she had ever seen the Lord trust someone else, let alone express his gratitude. The agent suggests that the player may have a positive influence on the Lord.
