The Temple Inquiry is a hidden World Quest and is a part of the overarching Hyperion's Dirge questline. To begin this quest, set your daylight setting to Evernight and ensure that you have at least one of each of the five different kinds of Key Sigils in your Inventory.
Head to the Evernight Temple with a battle-ready team—the exact location is circled in the map below. There, you'll find a clearing with five stones that contain the same symbols found in the Key Sigils.

Interact with the stones to offer them one corresponding Key Sigil each. An afterimage of Aberaku will then appear. Speak with Aberaku to learn that he was once imprisoned by a child in a very high place. But as his body was enshrined in various places due to his contributions in the creation of Helios, his spirit was rendered unable to rest.
He tells you that there are many perils up ahead in his quest for you, so he wants to test your abilities. Speak with Aberaku a second time to begin the Trial. You must defeat the prison wardens: one Rockfond Rifthound and two Rockfond Rifthound Whelps within 60 seconds. If you're unable to defeat the monsters within the time limit, you can try again or ask a friend to help through Co-op mode.
Completing the Trial will reward you with a Precious Chest. Make sure to speak with Aberaku again to obtain the Quest Item Offerings of the Temple.
