So idk if this is a thing or if I've been completely blind in the past, but in the Endless Steps, where the Ether Runner Servitor used to be, there's a weird Vex shield inside the cliff wall. It seems to be guarding some kind of passageway, cuz if you look through the shield, you can go through the opening and in to the right.
I'm just wondering, has anyone else seen this or found a way to get behind this and see what's there? If it's been there all this time, then I'm sorry for this post and I'm clearly blind as all hell.
