Description
You found this scroll on the body of the dead Guardian. This scroll contains information that the scout had observed about Meridian and its defenses.
Asha Catari will no doubt want to see it to assess what information the Guardians may have about Meridian.

You say you took care of this scout? Good. It troubles me that others may have been able to return to Sanctum with information like that found in this scout's notes, but I am glad to know at least this one in particular has not made it.
