Log Leave

Log leave (神隠し (ログリーブ)), also translated as log leap, is a phenomenon in which Adventurers who were transported to the world of Theldesia after the Catastrophe suddenly vanish without a trace and are displayed as inactive on friend lists.

Currently, there is no fixed method for triggering log leave: some disappeared after passing through Fairy Rings, while others went to sleep and then vanished by morning. Shiroe theorizes that these disappearances are likely voluntary, and may have something to do with the Genius threat.

What happens to those who undergo log leave is unknown; Shiroe's optimistic hope is that they've returned to their real world, but the only way to truly verify that would be to return to their world and come back to Theldesia.
