Side by side portals:
But you can also de-construct the generation of the portal and make it at a place that suits your needs
And finally, The Depths:
You craft the portal frame blocks for Euca and The Depths by killing the 3 Nether boss’s which you have to spawn in the Nether using these 3 items:
Withering Beast Orb
Nether Beast Orb
You will get a random amount of gems from the boss’s and its a 50/50 chance to either get Euca Gems or Depths Gems which make 3 block per 9 gems.
