The core would be a biome under the underworld where you would only be able to survive it with Solar Flare Armor. It would be made out of the Outer core it's a magma like liquid (basically lava) and there would be the inner core. The inner core would be iron! (since in real life the inner core is mostly comprimised out of iron)
Now i would suggest somewhere in the inner core there would be a portal. Once you go in its reach of 10 blocks there would be a boss coming out called "The burner of worlds" he would be basically be like the Solar Flare Armor... Except that's his skin. Anyway he would be a boss lived on the sun. And he would shoot out mini solar flares they would do ALOT of damage something that you could only survive with the Solar Flare Armor still don't know how much damage. Once you beat the boss you get his head which would be a weapon that shoots out 3 of those mini solar flares. They would kill enemies instantly but if not then it would give enemies a burning effect.
Anyways thanks for reading my suggestion!
