[@Kho] Seesh, that is a lot of responsibility.

Ok, I'd say the turn starts and the end of the Hain era, probably its last 1~ thousand years.
Humanoid Era, well, Notte mentions that by the time she was going to Jvan humans were already many generations down the road. Niciel's angels have similar posts.

I'd say overall we crossed 2~3 thousand years in the post. (The ending event being Toun's flood)
On my scale I will probably fuse Hain and Humanoid age together, the flood event really changed the way I was seeing the era.
