Reverie

I once had a dream about a Flight Rising 3D story mode. There was this whole thing about dragons going missing and you have to find them, but you can also explore 3D Sornieth, meeting up with NPCs and occasionally other players, finding treasures, and fending off monsters.

I remember there was this dragon duo famous for being thieves (They were a sand-colored Nocturne and a Ridgeback), and, whenever you found a chest while exploring the Shifting Expanse, there was a chance you'd get an alert saying they're coming and will steal your stuff and so you have to prepare yourself. In order to keep them from stealing your stuff, you could either hide, fight them, or bribe them with items they like (I remember the Nocturne liked bones, weapons, and silks, not sure about the Ridgeback).

I found a chest on a hill at one point, and I open it and find a Lightning Egg inside it. I was really happy until I got that alert saying the Nocturne was coming. I start freaking out because I couldn't hide and I sucked at combat in the game, and so I'm just searching through my inventory for anything he'd like. Eventually he came, and I managed to convince him to not take my rare, valuable Lightning Egg by giving him a sparrow skull. I then tell some other people in the game about it because I found it funny, and then they go, "Yeah, I hate it when they come after my expensive things. At least they become good guys at the end."

Hecking spoilers.

I also found a Lightning Egg a few days after having that dream. Spooky.
