The rise of Erebus book three by Judah 

Watcher materialized on a dark red landscape. To his surprise there was no sky just the same dark red. Mithrandos appeared next to him “ why is there no sky “ asked Watcher. 

“because the Nether creatures hate the light she answered. Just then a giant ghast floated upwards. Watcher recognized him immediately 

“Malacoda” he breathed. Malacoda smiled. Hello boy wizard he said with a sneer and shot a fireball at him Watcher ducked and pulled out The fossilized brow of destruction and shot at Malacoda the ghast instantly disappeared leaving some XP and the biggest ghast tear he ever saw (and the only one) Watcher continued on with Mirthrandos. After awhile Watcher said  where is the fortress immediately a tall fortress made out of the same red material as always. For a moment Watcher was confused how had that happened then he ignored it and went on after awhile Watcher reached the gate and peeked in dozens of blazes and ghasts and wither skeletons and zombie pigmen and magma cubes where crowded around something Watcher was about to step in when Mirthrandos pulled him back 

“just a minute” she hissed just the thousands of overworld monsters poured in followed by another set of monsters which included dozens of dragons and boxes that opened and closed 

“hello mobs of the dark” said a blood-red endermen. “To day we unite for as alwrese we will pact on the blood of a wizard as you no i am Erebus king of the endermen now should i draw the knife” 

“yes” bellowed the mobs 

“oh no” said Mirthrandos “ oh no oh no oh no “ 

“what is it” said Watcher 

“ you do not  want to no” said Mirthrandos “back to the portal” 

“but why” said Watcher 

“just go” said Mirthrandos but it was to late Erebus stepped back and Watcher gasped lying on the ground was Planter.
