More explaining the magic system. Theory 2: Spark spells are a derivative from old magic

The idea that pre-written spells are strictly. thing of new magic feels odd to me. I feel like jut based n her personality people like Redbud would have been experimenting with the concept of spark spells back in the days of hardcore old magic. I think the only reason it needed new magic was because a spark spell has a special quality: Spark spells aren't single use. I feel like because old magic has a very like "THOU SHALT RESPECT THE BALANCE!!!!" Kind of mentality to it, all pre-written spells or spells put on paper (That is sigils drawn onto physical objects and not just willy nilly in the air) Sort of like a steam engine required manual care, and manual energy. The user had to use their own energy to use the spell/use the artifact and in that case it was a strain on them. (Sort of like how a steam engine you need to shovel coal actively into the furnace, and that's still human labor). And therefore most "Spark spells" In old magic are like talismans, and are single use only.

Spark spells require new magic, because in new magic, terraspheres act like a battery, becoming the magic storage unit for cmplex spells. (Workign with the previous steam engine analogy, it would be like an electric car. Obviously you're still the one behind the wheel but the engine no loner requires active HUMAN labor to keep the enginge running, there is no "Active shovelling of coal or the train stops"). That said because of this battery these spells also don't pull energy from the talisman itself. (No wear and tear of the vehicle) which allwos the spell to be used over and over and over again because it's running on an external energy source. Because each repetition doesn't require "The balance" As the battery is handling it, spark spells can be more condensed, compressed, more powerful and used many times because the "Balance" Is pulling form the battery and not the user "Shovelling coal" So to speak.

(That is to say I think Old/New magic can be used in a way that isn't just allegory for "Liberal vs conservative" Political stances. and it is done in the show but still.)
