Forerunner glyph disc in campaign

Can someone tell me what the disc with the forerunner glyph’s all over it(almost like a decryption wheel) in campaign near one of the terminals is for?

I found one and still haven’t found any info online about it yet.

all that happened was Cortana said something about decrypting the data or something and nothing happened afterwards just some symbols popped up.

Which mission?

Honestly I don’t even remember which mission had what anymore. I played for 18 hours straight beating the campaign solo legendary. I’ll have to go through the missions on easy later to find it.
I do know that it’s in the first 5 missions if that helps any.

Requiem. Mission Bravo.

Truth be told, you’ve got my interest.

Please, deliver.

thank you for remembering for me. i now remember it is in the second mission point bravo like you said.
it should be located near or around the terminal.

Its in the area where you jumpstart the cartographer, in a cellar-style area of the center if memory serves.

I took it as a simple memorial plaque, but something that elaborated on the history.
