Welcome to the To All Churches Halcyon Grid!
Halcyon World is a Virtual World with a full 3D environment, where you may move about with a character(avatar) in a 3D World accessed with a 3D Graphics Application called a "Viewer," the most common of which is the Firestorm Viewer.
For example, here are two Screenshots of the Firestorm Viewer before login with two other Halcyon Grids selected, Amaryllis Grid & Gospel World. Which are in no way connected to this grid, and do not support this grid.
The OpenSim version of which can be used for this Grid, which is known as "FirestormOS" the 'OS' standing for "OpenSim" in this case, not to be confused with "Operating System" in other contexts. While this grid is not technically an "OpenSim" Grid with the ability to teleport between Grids, the FirestormOS Viewer still works for Halcyon Grids.
Since this is a new Grid, it has not yet come online yet for the first time. Though it should be online soon. So you can still create your account now, and check back later to see if it is online.
Thank you for choosing the To All Churches Grid.
