- The specific magical effects themselves — igniting stone or enchanted metal with a touch, “truth-light” that makes lying physically uncomfortable, dissolving illusions, or temporarily transferring heat immunity to another person — are fictional extensions of real chemical properties, not real phenomena.
- The Ember Familiar (a fire sprite) and Sylphrenna (a lightning-charged storm-fox spirit) are entirely fictional magical creatures.
- Ley-gate teleportation, Isolde’s river-warded fast travel, and Fenwick’s fully autonomous steam-powered mechanical raptor are fictional technologies and magic systems.
- The world of MarBryn itself, its single moon and the “Moon-Star,” the city and location names (Hollowmere Vale, Emberhold Spire, Kaelport, the Sunken Foundry, Glassmere Lake, the Obsidian Wastes, Ashenmoor Citadel), and the “no metal, no magic” philosophy are all invented worldbuilding.
- The villain’s “Cascade Array” — a device that stores and weaponizes harvested oxidative energy to age metal across an entire region in an instant — has no real-world counterpart and is a dramatized, fictional escalation of real oxidation chemistry.
