You would find a portal and jump in it which would bring you to New Dragonspire, you would sneak inside one of the End Structures, searching for the End Crystal's and to take them.

Few Endermen would be around, though you would easily sneak past, you'd continue wandering until suddenly you'd bump into Vordus, he's tall, towering over you, he'd slowly look down at you clearly annoyed about you're prescence.

"And where may, you. Be going?"

He'd ask calmly and firmly while scanning you up and down to see if you're a Ally Human/Frostbourne Member Or a Threat, a Nether Empire Member.
