Realm of oblivion

A portal made of nether brick and glowstone on the corners and it will pop you into a new dimensiion alot like the nether but with a new set of mobs, ores, materials, structures and bosses,
First the terrain should be a magma ocean, like the nether but, the only land are huge pillars of infected stone which spawn the infected (a new mob will explian later) if broken, on top of these pillars are oblivion castles, these castles look simaler to nether fortresses but much smaller and more rare, this is where you fight the infected soilders (also a new mob) and one chest in the center of the castile the chest contains the grim reapers head and some random loot. The infected is a orange silver fish with tumors, and the infected soilder lookes like a mutated villager, they drop infected flesh which can be brewed into a infected potion which gives poison II, blindness, nuasea, and weakness. The realm of oblivion on the spikes are silver which acts like iron can repair any tool but a very little amount, and is very shiny, there is also another ore called tumors, which drop infected flesh and alot of xp, and the last new ore, zink a ore that can be made into armor and if wearing a full suit it scares away the undead, but attracts creepers like a becon in the night,
