In that vein, the seithr magic championed by the Freya/Freyja of myth *was* pretty much exclusively 'woman's magic' (and dealt with mostly divinations, illusions, glamers, enchantments, curses, etc. no force fields or magic zaps) while men focused on forging magic weapons and armors or casting runes and changing shape. It was very sexist by some modern day interpretations, but could be presented a bit differently today.
Loki, unsurprisingly, was good at both 'men's magic' (shapeshifting) *and* 'woman's magic' (illusion, curses) because, surprise surprise, he's all about breaking the rules and exploring stuff that society tells him he shouldn't.
Both Odin and Freya were pretty territorial when it came to keeping seithr to approved people (in her case) and keeping the secrets of the runes to himself (in his case). Either sort of magic seemed limited to those who their respective patrons thought had 'earned it' and not just any schmoe with a bag of plastic Futhark runes they bought online.
