Now I will admit, this information is totally useless, but I’m pretty sure I am the first to discover this and at least the first to make an official statement online about it. But theres a secret ice cave in the northern lake I can’t find any information about online. And its not the gate into the slient legion keep. Its under the ice at the lake entrance to the glacier canyons, bottom left corner of G11. You have to swim back under the ice really far, it looks like a dead end but its not, swim down and under a wall of rock and you can come up under the ice in a big water filled hollow chamber. Too bad theres no way to clear water out or stay warm and breathe under water permanently. It’d be a easily secured, totally hidden base location.

Swim back under the ice.
It looks like a dead end but it isnt, swim down and under.

Sorry for the crappy pics, my camera is like 5 years old.
