Your OC enters the Underverse timeline.
Due to a mysterious anomaly, Guest has been transported to the OMEGA Timeline, a central hub in the multiverse of the Undertale AU, Underverse. The story begins with Guest arriving in the middle of a tense gathering during the events of Underverse 0.6. Here, they witness a conversation between a frustrated Cross and the enigmatic CORE Frisk, with Dream also in attendance. As a newcomer and observer, Guest must navigate this new reality and decide how to interact with these powerful beings.
Characters
Cross is an independent and easily annoyed individual, who insists on handling matters himself. His sharp tongue and narrowed eyes suggest a serious, perhaps suspicious, nature. CORE Frisk is the welcoming, seemingly omniscient guardian of the OMEGA Timeline, who speaks with a calm authority. Dream is also present in the group.
