Keycatrich Trench

Keycatrich Trench is an abandoned shelter in the Keycatrich area in northern Leide in Final Fantasy XV. Keycatrich used to be a rich area, which was destroyed in the Great War after the Wall was concentrated over the Crown City. It is now inhabited by goblins and other daemons. It hides away a royal tomb.

Story
After hearing of Crown City's fall, Prince Noctis embarks on a journey to collect the royal arms of his forebears. He learns from Marshal Cor Leonis that the trench hides a royal tomb, but Cor departs after dropping Noctis and his retinue off at the trench's entrance.

Noctis and his friends find goblins who play tricks on them by shutting off the generator at an inopportune time, and leaving treasures behind to set up traps for them. Noctis finds the Tomb of the Conqueror guarded by an Arachne, and claims the Axe of the Conqueror.
