How to use a precursor gateway:

• unlock the gateway system through the story or by using the command /se_allow_portals

• place an Ion-Cube on the pillar infront of the gateway 

• this will open up the gateway (only one way) 

• in the story all outside gateways lead to the sea emperor chamber but the sea emperor chamber has only one gateway leading to the mountain gateway

How to create your own gateway:

• use the command /se_create_gateway 

• this creates a gateway but you can also build your own gateway which need to have 4 frame blocks that mark the bottum/top/left/right and the portal terminal

• after that is done, use a nametag thats named after the coordinates and direction of facing when arriving and right click the portal terminal with it 

Example of the nametag name: 520 42 870 west  (x y z direction)

• after that all thats need to be done is activate the portal using an Ion-Cube
