So, one thing that I did notice was during the time of the Ice Palace, I found a hidden chamber. At the end was a war room, with a map- it was almost a copy of the one Elsword has, though it's notable that the Entity doesn't know what lies beyond the forest at all, and is incredibly confused by it.

It showed a temple, a church, and lake. Aldric's Grove was also noted, as was Moder's migration path and the start of where the trees get unnaturally huge.

It also seems to be afraid of the sea? Or whatever is in it.

I took pictures as well as drew what I could from reference and memory.
