'Nine Hundred and Ninety-Nine Nights' is a permanent large-scale mode added in NTE 1.2. Inspired by tabletop RPGs, it's set in a fantasy world called the Warren Continent, where you challenge dragons across difficulties and progress through tabletop-style chapters. It stays open permanently, is fully repeatable, and drops Ringstones and growth materials. Note it is not the same as the Amusement Park map — the park is a real area in the Hethereau suburbs, while the Warren Continent is a separate fantasy world.
