The Hollow: Season 1

In this animated series, three teenagers - Adam, Mira, and Kai - find themselves trapped in a strange realm filled with magic portals, perplexing puzzles, and vicious beasts. With no memory of how they got there, they must work together to survive and find a way back home. Along their journey, they encounter a mysterious figure known only as the Weirdie, who seems to be controlling the game they're trapped in. As they navigate through treacherous lands and battle fierce enemies, the teens discover that their memories are not what they seem, and that their only hope for escape may depend on their ability to confront the dark secrets of their past. Will they be able to overcome their differences and work together to escape this dangerous world before it's too late?
