Sorry for derailing but this is related to OP topic.
My character (Savage Worlds) is an astronomer who discovered that he can channel magic by aligning certain runes to certain positions based on the current positions of constellations/planets. He is constantly measuring and mapping these movements each night he can, while during the day (or indoor adventuring, like caves) he uses machinery with adjustable dials to "use" spells.
I'm looking for interesting ideas on the types of machines he could do for these spells/effects:
-Detect & Conceal Magic
-Summon (flavored as various monsters that are interpretations of or aligned with the constellations)
Thoughts, /tg/ ?
