Cave of Mastery secret area?

[Lightfireking]

So as most of you know after learning about Dragonpulses there is a daily in the Cave of Mastery which leads you to a not seen before area of the cave where the bear enemy Yo Gi is in. If you take a look at your map you will see that there seems to be another cave connected to Yo Gi's cave. Looking around you will notice that there is a stone overhang all around Yo Gi's cave, a stone terrace if you will. Wallrun on the right spot and you can somehow manage to get up there. There is not much to look at up there, other than an entrance that is blocked by stones. Secret area? Just something that was accessible during the main mission and i forgot about it? I don't know what it is.
