Links and Notes for Mangar’s chemistry inspired magical abilities:
Manganese oxidation states and the green-to-violet color shift (Mangar’s orb)
Mangar’s orb cycling from stable green Mn(II) to a violet-edged, highly oxidizing Mn(VII) state at moments of maximum power — mirrors real manganese chemistry closely. Manganese genuinely has an unusually wide range of oxidation states (+2 through +7), and the permanganate ion (Mn in the +7 state) is famous for both its deep violet-purple color and its strength as an oxidizer.

Manganese “purifying” sulfide contamination (the desulfurization climax)
Mangar’s final act — dissolving sulfide coatings and reversing sulfide contamination in the ley lines — draws directly on manganese’s real industrial role in steelmaking, where it’s added specifically to bind and remove sulfur impurities from molten metal.

Sulfide as a corrosive, weakening agent (the Corroded Ones’ weaponized coating)
The villain’s use of sulfide treatment to make weapons and infrastructure brittle and “corroded” has a real basis in sulfidation corrosion, a well-documented failure mode where sulfur compounds attack and degrade metal.

The Nodule Fields (manganese nodules beneath the Sulfur Flats)
Polymetallic (manganese) nodules are an actual deep-sea phenomenon: rounded mineral accretions of manganese, iron, nickel, and copper that grow around a seed particle over millions of years at millimeter-per-million-year rates, exactly as described in Chapter Eight.
