Corona is a now-defunct development group which formed in early August 2004.
The development group Corona announced themselves on the day of a solar eclipse, hence their name. They followed quickly the next day with the release of their first metaroom, the Garbage Dump, which was designed especially for Toxic Norns. The graphics were produced by the team's graphics artist Moe who had worked closely with edash since October 2002 on a project called The Canopy. AquaShee joined the group in August, two years later; the three members combined chose a name and began work on some of the projects and agents that you find around the Creatures Community today.
On April 8, 2007 it was announced by Moe that the group had "pretty much fallen apart".
