Eternal - The Forever-Sleeping Forest Episode 5

Lina and the gang follow Pokota into a forest that suddenly grows misty. They end up encountering Xellos, who is wandering in the woods. The mist reveals a lost city of Tarofshia whose inhabitants were put into suspended animation by Rezo the Red Priest (yes, that Rezo) in order to save them from a disease that was incurable back then. But strange things are amiss as Pokota discovers that someone's invaded the king's mansion.
