What is the Lonely Player in NTE? How to trigger this event?

The Lonely Player is a hidden NPC event/easter egg in NTE. In specific locations around Hethereau (park benches, rooftops, subway stations), you'll encounter a solitary NPC. After multiple conversations, this triggers a hidden quest chain telling a touching story about loneliness and companionship. Completing all dialogues and quests grants Ring Stones and a hidden achievement. This easter egg pays tribute to lonely people in city life, resonating with NTE's supernatural urban theme. Look out for NPCs in corners while exploring — there are more hidden stories to discover.
