- The expression to "spirit away" means to remove without anyone's noticing. Kamikakushi (神隠し, hidden by god?) means "spirited away". Kamikakushi is used to refer to the mysterious disappearance or death of a person that happens when an angered god takes a person away. In pre-modern Japan children would often disappear in this way and be rediscovered several days later in a shrine or temple, consistently telling a story of being swept away by a god. Lightning's disappearance to an otherworldly realm governed by the goddess may harken to this folk designation.
- Atlas is a reference to Atlas, a Titan who rebelled against the gods and was punished to hold the sky on the western edge of the world.
- Lightning's story is set in Valhalla, "a realm beyond time" where the temple of the goddess is placed, in which she fights alongside her Eidolon, Odin, repelling attacks from Caius. In Norse mythology, Valhalla is the hall of the honored dead who will fight for Odin at Ragnarok.

- Serah's bowsword and Noel's dual swords are called in the English release "Odinbolt" and "Odinblade" respectively, but in the Japanese release they are known as "Takemikazuchi" and "Futsunomitama". Futsunomitama is a sword said to have been wielded by Takemikazuchi, a thunder god, in his campaign to bring order to Ashihara-no-Nakatsukuni in ancient Japan. The English descriptions for both weapons allude to this connection as Odinbolt's description says that it is "named after the wargod of storms" (somewhat coincidentally in Final Fantasy XIII trilogy Odin is an Eidolon associated with the element of lightning) and Odinblade's description states that it is a weapon that "crackles with almost divine power".
- When the Academia receptionist tells Serah and Noel to choose between Odinbolt and Odinblade, she was joking about giving them an option to choose a large box or a small box. This is a reference to the tale of Urashima Tarō.
