The underground ruins used to be a city of the elves, which had sunken underground after the seven Gods' invasion.
At the same time, it had been stuck in a completely sealed state since then, displaying itself for the first time in a thousand years.
Chromie could sense something calling out to him from inside the city, which led him to feel doubtful about his Farnate family's relations to the elves.
The Moonlight Ring was his family's heirloom, and he had just instantly learnt the language of the elves and sensed the call from inside the elven city at the same time.
Chromie's gaze appeared a bit hesitant, the scene of the elven race being killed to extinction by humans once again appeared in his mind.
The people who destroyed the elven race were very likely the current seven churches.
