Orion's Arm

The Orion's Arm Universe Project is an online collaborative fiction setting which describes itself as a transhumanist Space Opera with many worldbuilding elements. The year is 10601 AT (probably), with the AT calendar beginning on the day man first walked on the moon in 1969. This means it is ten and a half millennia in the future, and as you can guess, the far future is an extremely weird place, where the only boundaries are imagination And physics.

Dyson trees are a megascale bioengineering concept. A fully grown tree is a spherical structure up to a hundred kilometers across. It generally consists of 4-6 trunk structures growing out from a comet nucleus. Branches grow from the top of each trunk and intertwine and merge with each other to form a single structure. The trunks and primary branches are hollow and contain a breathable atmosphere and symbiotic ecology as well as a space adapted ecology on their exteriors.
