I do not know if this is the correct place to post this, but I have a feeling it may be lore related. When you enter certain Realm Reborn areas (Sylphlands, The Unholy Heir, Lowe La Noscea also I think) there is a sound that rises...a low humming or moaning. What causes this sound? Perhaps a shard of Dalamud? Perhaps an area where a Primal has been summoned? Perhaps my client software is broken ?? I have always wondered what this sound is and have never seen any discussion of it elsewhere...a definitive answer would be appreciated from anyone that knows. Thank you.
