Ancient Forest

The Ancient Forest is a location in Final Fantasy VII just southeast of Cosmo Canyon. It is unreachable during the first part of the game. The only way to get there is by a green, black, or gold chocobo, or by defeating the Ultimate Weapon. The Ancient Forest is basically a large logic puzzle. It contains many rare items (including Cloud's sword, the Apocalypse, which has triple materia growth) and rare materia (such as the Typhoon summon).
