Nightmare Expanse

The Nightmare Expanse (or simply known as the Nightmare) is a realm within Randumcraft. It is known to have the most dangerous mobs in the entire game, let alone the player's level. During Tyr the Legendary's quest, adventurers are sent here to recover Nightmare Eggs to help him assemble Skullmourne. In addition, players can train here with friends to best the monsters within, though their drops (other than a highly low chance of it being a Black Glazed Terracotta) lack anything to be desired.

Entities
All entities within the expanse have an ?? combat level.
 * Unstable Nightmare: Charged creeper mobs that are invisible, only able to be spotted by their lightning signature. They are silent and fast but have a low detection rate. If one explodes, even with the best armor, it is fatal.
 * Unstable Witherer: A charged creeper mob that leaves a deadly linger in its wake.
 * Reality Phenomenon: An enderman mob that constantly decays and is lethal to the touch.
 * Reality Destablilizer: An invisible enderman mob that attacks in swarms.
 * Abyssal Watcher: A shulker mob that launches explosive orbs that send people levitating upwards.
 * Nightmare Fiend: A wither skeleton mob that constantly decays areas around them.
 * Screeching Terror: Phantom mobs that deal rapid damage.
 * Archterror: A giant, floating phantom that deals lethal damage.
 * Wither Omnis: The "bosses" of the area. Drop guaranteed terracotta blocks, though are very dangerous, lethal mobs.
 * Nex Angel: Small, hostile entities that swarm in groups.
