In the Pokémon Adventures manga

Eterna Forest first appears in Robust Rotom. Diamond, Pearl, and Platinum trek through the forest on their way to Mt. Coronet. Pearl wonders if there are multiple paths through the forest, only to learn that there are no paths shown on Platinum's Town Map. After reading a tourism guide book, the trio learns that it takes more than a day to pass through the forest, and that there are no lodgings to rest at. Pearl, fearing that Platinum will cry if she has to sleep outside, runs off with Diamond in toe only to discover a large manor that was not mentioned in the guidebook. The two spot two hooded figures near the manor, but they suddenly disappear, frightening them both. Platinum then arrives on her Ponyta and declares they'll stay at the manor for the night, assuming that Diamond and Pearl were trying to fool her.
