Now that gets Ignis' full attention. The Dream Width pulled him back, gave him some of the memories back and returned him? That is distressing to hear. And it could be what happened to other people that disappeared as well. Only... they didn't hear a word from them since. Did they get lost in Dream Width because there was no one to find them?

"It is good to see that you are alright," Ignis says with a nod. He's not going to pry about what kind of memories Shiro retrieved.

Then he looks back at the painting: "Ultros... on Eos, we do not have the Astral, or rather, Eidolon, with that name. The Great Six that watched our world were Titan the Archean; Ramuh The Fulgurian; Shiva the Glacian; Leviathan The Hydraean; Ifrit- the Infernian and Bahamut the Draconian."

The Six that promised to lend the Chosen King a hand in banishing darkness yet got Noctis' life in danger instead, Ignis thought sourly.
