Ilex Forest

Ilex Forest is a dense forest located in southern Johto, directly west of Azalea Town. The forest's trees are so close together that all light is blocked out, and in Generation II, the forest seems to be in a perpetual night. There is a shrine for the guardian of the forest, Celebi. In Pokémon Crystal, if Kurt has already examined the GS Ball, placing it in the shrine will cause a level 30 Celebi to face the player. Though the GS Ball was never distributed as an event item outside of Japan, the Virtual Console release of Crystal allows it to be obtained in all regions through normal gameplay. In Pokémon HeartGold and SoulSilver, the shrine also may initiate a special event in which Celebi will take the player back in time and allow them to battle Giovanni.
