Crucible of Magnux

The Crucible of Magnux is a powerful and unique mythallar that can seemingly be transferred into different spheres, of which is usually an integral part of a mythallar, as much as the internal forces of magi inside.
The Crucible is capable of several incredibly powerful feats, as observed during its time in Raskburg, such as an almost complete block of communication ad teleportation in and out of the city through magic, as well as creating an artificial day and night cycle, and other implied protections that the city enjoyed.
Several groups and individuals, particularly Gemsmiths, have sought the Crucible, such as Dromis Khar for the purposes of fighting back the invasion of Sanguisica, and the Order of Nine, for an unspecified purpose.
