Past Cocona Village
Using the time-travel monument located in western Cocona Village, which was the Cocona Plaza in the past, Celebi will send the playerback in time to past Cocona Village. One major difference between past and present Cocona Village is the gate on the northern-end of past Cocona Village, which appears as a pile of ruins in present Cocona Village. The gate connects to a part of Teakwood Forest that the player is unable to explore in the present and leads to a warp-point to any of seven temples in the past and participate in Wireless Multiplayer Missions, courtesy of Kira. The temples were built to worship Arceus.
