Fate/Grand Order Lostbelt No. 5: Atlantis

Kirschtaria, the leader of the Crypters, controls a Lostbelt rich in giant relics left by the gods.
Its residents are strong, godsfearing people who stand firm even in the face of the Demonic Beasts which threaten the region.
It is a place dominated by a civilization that once stood at the height of supremacy, but is now little more than a shadow of its former glory.
All that remains finds itself adrift in a vast ocean.
That ocean's name: Atlantis. This world, in Proper Human History, is said to be one of the lost ancient civilizations.

A grueling conflict where both sides leave nothing in reserve ensues in the fifth and largest Lostbelt yet.
It is said that this day will see a god brought down...
But will that foretelling bear fruit or wither on the vine?

The first half of Lostbelt 5.
