anyone know where an end portal is?

There's a few. I use /l spawn endP but if your using eaglercraft it may not work due to it being bellow y 0

/L spawn endgate

endgate not working anymore I know one at /l spawn zNikollsshop and one that my friends found (its private)

/l spawn endportal (i found it myself :D)

/l spawn endgate only leads to my base lol
