Freljord/Howling Abyss event consept

I had an idea about a Freljord event. If you didn't know it is this door with a lock in the Howling abyss map (ARAM map). Link for picture: http://imgur.com/QDsmWrp

In the Event it could for example be someone that found the key to this lock and found some hidden things like the two watchers Avarosa and Serylda. or maybe an item that could change everything in freljord and maybe get a glimt or maybe a flashback from someone that lived at the time the Watchers ruled and see what the Freljord was back then and how everything went through. i think that would be very cool.

I would love to hear what you think should be the next event.[slayer-pantheon-thumbs]
