A small mod adding the altar, pedestals, and new enchanting methods.
The mod is available for Forge for 1.19.2 and 1.20.1, and Neoforge 1.21.1.
It is also available for Fabric for 1.20.1 and 1.21.1.
There was once a version for 1.18.2, but it was reworked so much for 1.19.2 that
the old version has been removed.
