About this game

The developer's description, from the game's Steam store page.

Diana's sister Luna and her father Robert were once among the greatest knights in the empire, but Luna left her nation behind, and her father has been stripped of his honor. A sorcerer now whispers into the emperor's ear and conducts unspeakable research to fuel the empire's insatiable need for conquest. In order to aid her father and better understand her sister's decision, Diana sets out to become an adventurer, her first step on the path to becoming an imperial knight. Will she find new friends and earn her knighthood, or be betrayed and fall prey to the empire's dark underside? The choice is yours!

Explore new regions, fulfill requests for the Adventurers' Guild, and fight in turn-based battles!

Along the way, you'll meet allies who will join you temporarily. They can then be hired as mercenaries to accompany you on your adventure!

Swap between day and night as you investigate towns, gather clues, and unravel the many conspiracies plaguing not only your family but the kingdom at large!

Become an Imperial Knight

The Ether Knights are the strongest force on the continent. Regardless of the path you choose, you can become a powerful knight who either works for the empire or strikes against its darkness!
