Also at Ilya island there is similar thing, and island across it... Someone told me this are arenas? There should had been some better immersion with this... Like larger walls or suitable terrain and not invisible walls...

I hit one too yesterday, figure its just content we cant access yet

While exploring Lema island. I found a giant stone castle wall. But also invisible wall preventing you from entering. Place looks mostly empty with some tents, but you cant even get close to wall.

Apparently it's a PvP arena that guilds can hire out and send invitations to other players to do arena based competitions like 2v2, 3v3 etc. It's not on the Xbox yet so I'm not really sure what it's actually like.

 

Looking now I think that might be a different island, but theres definitely an Island with a large walled arena you can't enter.
