Indoline Murals is an Info Item in Xenoblade Chronicles 2. It hints at the location of the Mysterious Part D. It can be obtained by examining the mural which is on a wall behind some tents in the northwest corner of the Refugee Campground in the Indoline Praetorium.
Once the Indoline Praetorium becomes inaccessible, the Leftherian Murals may be used to obtain Mysterious Part D instead.
