New Requiem Easter Egg?

I dunno if this is an easter egg or not but on requiem as you get to the part where you have to activate the cartographer in the middle part of this room there is a space where you can go under the middle walkway.

when you walk into this space at one end of it there is a circle shield looking thing that has glyphs, i believe, that say press x to examine. after that the chief asks cortana what it says. and its says something to the fact about the mantle of responsibility.

Is this new or have i just not seen anyone mention it?
