The Cave of Whispers is located near the Spirit Jungle. It's a famous place for spelunkers due to the number of caves that are scattered throughout the area. The Cave of Whispers has existed for more than a millennia and it had history records that matched its timeline. It became incredibly popular since it was believed to have been the hideout of adventurers in the past during the Great War. People of Lucid believed that countless priceless treasures await in the caverns, waiting to be found by those who are adventurous enough to venture into the unknown. These treasures, although not proven to be true, made adventurers a bit desperate to strike it rich. That's why they aimlessly explored the caverns without the permission of King Linhradth even though he advised them not to do so.
