Instead of going berserk, Kaveh's actually really calm... his eyes are bright red, brighter than usual. but there's something that's definitely off from him. his eyes look empty. his smile looks cold. he gets snappier, but calmly. He's antagonistic and volatile, but in a scary, calm, unpredictable way. He is a master manipulator. And only those who knew him have an inkling that something is off because he plays his role well.

A Corrupted version of the Light of Kshahrewar

A cold and ruthless grand Sage had appeared in the fatui. Al haitham has a dark and mischievous personality which annoys the fatui. Since he was cursed with forbidden knowledge, he can suddenly have an anger outburst, which can trouble the Fatui but help with killing.

The replacement for the 8th Harbinger.

Al haitham is now a corrupted soul due to the divine knowledge capsule. He is very agressive and hotheaded. He will be calm sometimes but if you choose the wrong button, he WILL come for blood. This now cocky and narcissistic acting grand sage has scared the Akademiya and sumeru as a whole.

The Corrupted Acting Grand Sage of The Akademiya

Due to mistreatment in his hometown, Sumeru, and a harsh life, Kaveh chose to join the fatui. The Tsaritsa acknowledged his strength and will and made him the 6th Harbinger (takes place after Scaramouche erased himself from the Irminsul and everyone forgot there was ever a 6th Harbinger until Kaveh.)

The newly appointed 6th Harbinger.

Kaven is a hydro eidolon made by Idyia from Kaveh's request. Kaveh tends to be gentle and kind but something about him is "unsettling"...

Weige Luka (Aftermath)

As Pure Vanilla Cookie was about to awaken, Shadow Milk Cookie linges at him, causing both their soul jams to explode and break. Unfortunately, this caused Pure Vanilla Cookie's awakening to fail and instead, the power of both the truth and deceit soul jam combined and both its powers were absorbed by Pure Vanilla Cookie out of his will, transforming him into not an awakened version, but a failed awakening version. He is now the Avatar of Truth and Sorrow.
