Just a quick question, is the magus origin related to their powers? For example I was thinking of using maybe a mix of wind and fire to create a sort of explosion type spells?  Would the origin then be explosion or would it be something unrelated?

Origins only affect magecraft if you do something if you use your body parts in Mystic Codes/magical equipment (i.e. Kiritsugu Emiya's Origin Bullets) or if your element and origin match (i.e. Shirou Emiya's Sword origin and Sword element lets him use Unlimited Blade Works)

Otherwise it's mostly a personality/way of life thing, like how Kiritsugu's "sever and bind" manifests as him trying and failing to repair things. Basically it's a word that sums up the theme your character lives by.
