[story][rfc] Fallout from The Gauntlet

[Proginoskes]

This is only a suggestion, but perhaps Fenspace has extremely low background mana levels everywhere, and no leylines, nodes, or Tethers to speak of. Handwavium can be used as a readily available mana source, but it "'waves" the spell to impose a Quirky side-effect or restriction (causing the spell to fizzle in various humorous ways if not met) that is consistent only with regards to that mage and that spell (and maybe even that strain of Handwavium). Certain magical fields of study are completely overtaken by Handwavium itself: magical Artificing, Alchemy, and Potionry are replaced entirely by Wavetech engineering, materials science, and chemistry, respectively. Under this scheme, spellcasting for Fenspace-native mages is effectively applying a 'wavejob to the local fabric of reality, which the universe eventually repairs back to cosmological baseline.
