With a boat driven by Cid, Noctis and friends crossing the vast sea to get into Niflheim region. They are planning to take back the crystal needed to reclaim the throne of Lucis. From the shore, they took the train to that will directly take them to capital of Niflheim kingdom, Gralea.

 

On the way, Ignis inform that Aranea bring Luna's death body back to her home at Tenebrae to have a proper funeral. Noctis then plan to pay a visit to House Fleuret at Tenebrae which lead to Noctis having a quarrel with Gladiolus, telling Noctis to stop thinking about himself and start caring about others who also ended up losing something, in this case Gladiolus refering to Ignis who lost his sight. Ignis suggest they will make a stop for Cartanica before going to Tenebrae to visit another royal tomb and get another royal arm for Noctis. Eventually they made it to Cartanica and decide to explore the mine underneath to find the royal tomb. On the way exploring the mine, Gladiolus seems to still having a grudge with Noctis for not being care about others.

 

At the end of the mine, they find the royal tomb guarded by a Marlboro monster. Even though Ignis is blind, he managed to analyze enemy weakness and put a good use to it. Ignis then will gain the ability of Libra Scientia. Ignis will also make a statement to stop worrying about him, he will go with everyone despite being blind.
