Ancient Observatory
An alternate Stage 5 environment set in a dormant celestial observatory, overgrown with glowing plants that sort of resemble the starry night sky.
It's a wide and expansive map with rolling hills, cliffs and large multi-layered buildings to navigate. There are launch pads scattered throughout to help with getting around.

Simulacrum
There is also a Void replication of Ancient Observatory with some (very) minor changes, exclusive to SotV's Simulacrum gamemode.

Music
Ancient Observatory has a unique music track, 'Orb Knowledge', made for the stage by Jared Damron (@FakeBees on Discord)! You can check out his other music on his YouTube channel.
