The planet Daydion is a nice place, if you like ice. Located a bit too far away from a dim star, its mean surface temperature is well below freezing. The system was not colonized for its planet, though, so the first settlers weren't much worried about that. The wormhole is at the L4 point of the system's only gas giant, Esus. The moons of that planet, along with very dense asteroid belt between Esus and Daydion provided materials for the first settlers to build orbitals with. Over the centuries, the sprawling orbital factories have come to specialize in computing equipment. The best equipment in the sector is produced here, and "Made in Daydion" is a mark of quality, in the same way that "Made in Binf" is sign of shoddy products.

About 80 years ago, a small group of asteroid miners and prospectors inexplicably decided that they'd like to colonize Daydion. Even less explicably, other people thought this a good idea. About a quarter of the system's GDP is currently going into terraforming of the planet, an effort that is optimistically predicted to take two millenia. Massive solar mirrors have been built, and even more are under construction, to increase the surface insolation. The process of figuring out what the biological processes of the terraforming is less well advanced.

The terraforming effort is even more amazing, because the orbitals's goverenment agree on little else.
