Davis's doppelganger returned to the obsidian flying palace eventually after a long journey.
Since this doppelganger was created through the insights he gained from Nadia's species technique, it was a clone rather than an avatar.
It doesn't have a mind of its own; should it be separated and would naturally expire once the time limit was up, which was extremely high. It was more probable that its energy would run out first and disperse.
The doppelganger traversed the spatial layers, going through multiple sublayers like shifting through a palace full of silk curtains and then choosing to stride between a row of stands that contained silk walls. After what seemed to be a long time, he eventually pierced through a fabric of silk- a spatial wall- and appeared out of a spatial crack, and what was standing before him was his avatar body and Fairy Qiyra Darkstar.
"Is anyone following you?" Fairy Qiyra Darkstar asked.
