The Stronghold is the first mission of the Minecraft DungeonsEchoing Void DLC. Unlike all other DLC missions before it, the mission can be found on the Mainland tab, on a very small island near the small continent.
A FORGOTTEN PORTAL – A long-abandoned Stronghold has suddenly become a hub of activity. That can only mean one thing - something ominous has awoken within. Solve the mystery that lies within to find the path forward.
What dark force conspires deep in the depths of this abandoned Stronghold? As you enter these depths, you start to feel as if the very void itself is watching. But now that you’ve begun, you must follow this path to the end — No matter where it leads.
The Stronghold is made up of stone bricks and wood. There are several pathways and brides over bottomless pits. The stone is covered with ripped blue carpets and Silverfish can be seen falling from the roof. In the middle of it all, the End Portal sits levitated over a pit of lava. Unlike the original game, though, it has two sets of stairways leading up to it. When the hero clicks on the portal it will make a banging sound, and if it is not activated, a menu will appear saying you need to collect the eyes of ender.
There are also paths leading away from the portal that are blocked off and say the following message if the hero clicks on them:
This Dungeon Is Sealed! Return to camp and search the Overworld for Eyes of Ender and return them to the End portal to explore the area beyond.
