Nexon posted an interesting message on Facebook earlier this day. Including the picture above, they posted:
In September, a boy with no name becomes the Knight of Light. Who could this be?
For the people who have been playing KMS or following KMS blogs lately it’s obvious this is the upcoming playable class: Mihile, Knight of Light. Mihile (Mikhail) was released as of March 22 in KMS. Mihile is the leader of the Knights of Cygnus, and is a warrior (hence he’s your ”master” as a warrior KoC).
This is actually most of the information I can give you for now. I will give all of the details when I know more (which is probably when the class is released to GMS).
