The Ferroverse is one of the verses that created the Palladiumverse. 3.1% of all matter in it is iron. The iron is concentrated in planet's crusts and galaxy dust, however, most of the iron is in iron planets. Iron planets are 79% iron on average, and they were formed when the gained iron got smashed by the Ferroverse's boundaries. The Ferroverse has 4 Forest Orb Verses, which were created by Zalkitans.
The reason it has so much iron is that a superplanet the size of 5.2 billion ly. It was composed of 98% iron and 2% titanium collided with the Ferroverse. Because the Ferroverse's attosphere are a grid of polygons that are ~30,000 km apart, the superplanet smashed in the attosphere and shattered the superplanet in ~300 km wide iron asteroids. The iron planets formed the same way as normal planets. They collided with each other and formed the planets.
The reason it is 79% iron, is because rock asteroids also collided with the iron asteroids. Iron also ended up in the crusts of some planets, while still retaining the shape of the planet. This is because when the asteroids entered the polygon border, some of them smahed into ~300 m pieces, that are called mini-asteroids, that don't do very much damage to the planet, and in the planets that got collided by the mini-asteroids, there are 300 meter iron deposits in their crust.
This universe contains planets, stars, galaxies and any other form of matter and energy, just like our Universe does. But everything is a little different from it's real world counterpart of our Universe. Stars, are however, pretty much the same ones, as those of our Universe. Planets are the most different things.
Some important planets are Cobaltia and Zalkitm. The civilizations of these planets are much more developed than us, humans and probable have better knowledge in science and technology. They are likely very different from humanity as well, and maybe more intelligent.
Cobaltia is one of the few planets that have cobalt, life and that isn't a cobalt planet. Cobalt is in one of the layers of the iron superplanet, because of the pressure. The cobalt broke when entering the attosphere, and smashed into pieces, forming cobalt planets and planets with cobalt and most of the times, iron. Cobaltia has a kardashev scale of 2.38, and despite their low KS, the civilization in the planet (called Kobaltia) conquered 3 solar systems, and created a perpetual energy machine, that can only be created with cobalt, an element that most planets don't have access to.
Zalkitm is a planet that contains arsenium, an element thats necessary to make Vacuum Decay protection technology (cadmium can also be used to make VD protection technology). The arsenium, like other elements in crusts of planets in large deposits, came from the iron superplanet, and the arsenium came from a deep layer (even deeper than the cobalt layer). Zalkitm has a civilization called Zalkitan, and have a KS of 3.15. They made VD protection technology and sell it to civilizations that don't have it.
Duocofe is a binary planet system. Duocofe A (known as Duofen) is a planet that has deposits of iron, while Duocofe B (known as Duocon) has deposits of cobalt. The Duocofe system was colonized by the Zalkitans, but because there was no original civilization, the Zalkitans only used it to mine cobalt, which is an element required for the ceration of perpetual energy machines.
