Notice: There are three sources of 'energy' for our Space Magic. Arc Light, Void Light, and Solar Light. The initial offerings of subclass only cover two of those energy sources, which likely means; at the very least, a third subclass of each of them. Possibly an end game subclass may exist incorporating all three energy sources into one synergistic subclass of devastation (Never cross the streams!). [EDIT: They are all called Light instead.]
