- “Refers to monsters falling from the moon. Completely destroyed the cities of Centra. Occurs when monsters reach a saturation point on the moon. It's believed that there are factors on the planet that cause this phenomenon. This phenomenon has occurred many times in history and will reoccur in the future.”

According to the Final Fantasy VIII Ultimania the cycle began tens of thousands of years ago; a product of gravity, the phenomenon is similar to the pull on the tides; when the moon's surface reaches saturation point with monsters it spills and falls to the planet and can destroy entire nations. The natural flora and fauna may change drastically; it has also been mentioned creatures can undergo change by being in touch with the monsters of the moon.
It is said that when the Lunatic Pandora is in perfect alignment with the moon the Lunar Cry can be performed, and monsters will be summoned to wreak infernal havoc on earth. Lunatic Pandora was constructed under Sorceress Adel's rule, likely to be used as a weapon in the Sorceress War. The only known incident of Lunatic Pandora having been used to induce Lunar Cry under Adel's rule occurred in the Trabia region.
During his movie-making adventures in the Vienne Mountains Laguna Loire spotted the Lunatic Pandora in the distance, although he didn't know of its significance. Two men talk on this instance of Lunar Cry on the bridge in Esthar City during Squall and his party's first visit to Esthar. This Lunar Cry over Trabia is what likely caused the crater near Trabia Garden.
Seventeen years after the end of the Sorceress War, Seifer, on Ultimecia's orders, steers the Pandora towards Tears' Point to induce the Lunar Cry with the intent of bringing Sorceress Adel's tomb back to earth. Esthar is flooded with monsters that overrun the country and Esthar City, causing massive casualties, as well as turning the sky red.
When the Lunar Cry sequence takes place, the track "Tears of the Moon" plays. It is the 18th track of Disc 3 in the original soundtrack.
Luna is the Latin word for "Moon".
Lunar Cry thus refers to the cry of the moon. It is called Moon Tears in Japanese and its musical track is "Tears of the Moon", the monsters being the "tears". When Lunatic Pandora docks at Tears' Point a statue of a woman cracks along the corner of its eye, alluding to this.
