Sterling's Sanctuary: Heavens Womb

The daughter of the CEO and creator of the world famous DMMORPG, YGGDRASIL, decided to help the company by creating an event. In this event, she collaborated with the devs and created a boss so powerful that virtually no one was able to beat it. Entire top guilds tried to clear the boss stage, and failed. If anyone did somehow manage to defeat the strongest raid boss, the boss would allow the player to get absolutely anything within the game, essentially granting them a wish in-game. The main character could even control the boss during times in the game. But now, the game was coming to a close and our main character decided to simply enter the game one last time to bid it farewell. But something went wrong and she ended up getting isekai'd into the New World as the Grand Oracle, Annalisa Astrid Sterling.
