They probably should have picked a better place to build Sanctum.

Apparently Sanctum of the Vigil is built upon a crater with a lake at the bottom. What is supporting the building to keep it from collapsing into its watery shallow grave? Clearly our guardian engineers are either very smart to keep a building as heavy as the sanctum up, or were lacking something when these blue prints were designed.

Furthermore, perhaps Sanctum of the Vigil is protecting something that is hidden within the lake. What could that possibly be? hmmmm

lol precarious isnt it

Hmmm maybe there are plans to make a future Lantern Hook style instance under Sanctum? ie The Fall of Sanctum?

0.0 We can't let sanctum fall! That means the guardians lost!

I've heard of this mysterious lake that only makes itself seen to the gifted few! I wonder what sorts of treasures can be found within the lake? What about adventures? Quite exciting if you ask me.
