I have just constructed an ender portal somewhere in the world, it is active and eye of enders to lead to it. But there is also lava surrounding it, so be careful (and have fun)

and just a little warning, as the end is very small in size, and griefing will be quite common. I might reset the end sometime in the future if the need arises, just so you're all warned not to build huge fortresses or anything there (Xestia!)

Where is the end portal may I ask you?

The coords are secret, but you can find them if you read the wiki

what does it mean "the location is split in three"? Do the eyes lead to the portal or just some riddle?

It's kind of a riddle, the idea is that it's a quest that takes you a bit around some various places on the server.

well if it's in the range that strongholds are in, 1K-5K if i remember right, i'm not going there any time soon.

It is indeed in that range.
