[X] Seed the Cosmos with Strange Minerals and Metals (Cosmic Act)
Every star in the universe produces some amount of Solar Magic. It is a byproduct produced by the process of Nuclear Fusion, but the Solar Magic one may acquire from the stars at night is only an infinitesimal fraction of the amount one may receive from the bombardment of Solar Magic from the sun at day; all the other stars are simply too far away that their Solar Magic had been spread too thin. The stars that shine the brightest are oft the most Solarly Magical.
When Solar Magic touches bare rock, it may transmute the mundane rock into Moonstone, but any amount of cover, may that be air, water, or organic matter, will block the Solar Magic from transmuting rock. The transmutation seeps into the bare rock, transforming rock up to a meter deep into Moonstone.
Moonstone is a paler version of the original rock. It transform Solar Magic into Lunar Magic, and the light reflected upon its surface shall become Magical Moonlight, carrying the power of Lunar Magic with them. It weakens the boundary between the Seen and the Unseen, allowing matter from one to easily cross to the other, and the Moonlight carries this property with them, weakening the boundary on wherever is illuminated by the Moonlight. Moonlight from Moonstone shall bring the same effect as the moonlight of the moon of the first world to any thing, affliction, or phenomena triggered or affected by moonlight such as the curing of the stone plague.
It may be brought down to earth by meteors, but water and salt tends to leach the magic from it, returning them to their original mundane rock.
Lunar Magic is strongest on the full moon because more of Lunar Magic being produced on the moon's surface is directed towards the world. The crust of the moon of the first world is wholly made of Moonstone.
The cosmos shall be seeded with various minerals and metals. They may be strange, extraordinary, or perhaps simply unusual. They shall serve as supplements to mundane substances as well as the wondrous materials the elemental forces may produce.
Stillstone is Moonstone that has been corrupted with elemental Dark. It is radically different from its parent material, having chalk-like softness and a pale yellow complexion. It strengthens the walls that separate the Seen and the Unseen, disallowing many from between the two. It will react with water turning into an ineffective form, but will be returned into its effect form by submerging it in sulfuric acid. It readily dissolves in oil without losing effectiveness, allowing one to effectively increase the volume of their Stillstone.
Bonestone forms skeleton-like deposits in the ground. The creatures their skeletal deposits depict are often awesome and intimidating creatures which does not exist, and any resemblances to real creatures past and present are simply coincidences. Bonestone deposits have a spirit of their own and are quite receptive to Legends. They can magnify even a small rumor attached to them and turn into a full-blown Legend.
Mithril is a metal chemically indistinguishable to silver but magically different. It absorbs magic, weakening spells but also chipping away curses. When polished to a mirror sheen, it only reflects what things truly are, removing all magical illusions upon its reflection.
Adamantium is a magical variant of titanium possessing extraordinary hardness and stiffness. Its raw ore form is simply too impure to display its extraordinary properties. Once purified, one may find that no mundane blade can cut or scratch it, and any blade forged from the metal does not warp or dull easily. However, it reacts readily with air and quickly becomes impure and weak.
Orichalcum is a dull opaque metal crystal with superconductive properties that doesn't lose effectiveness in high heat. However, such properties may not be apparent unless green rocks is amply pure. It is a magical variation of lead, osmium, and tungsten, differing mostly on electrical properties from their mundane cousins.
Nodes and veins of Stillstone, Bonestone, Mithril, Adamantium, and Orichalcum shall be spread across all worlds, moons, and other rocky celestial bodies in various amounts.
