End Ruins

When you enter an end gateway portal you should be teleported to a kind of ruined End Village. In these ruins there would chests consisting of loot such as emeralds, saddles, and enchanted books such as mending and more importantly a chest with map to an Endcity. Most of the time we have to search thousands of blocks to find an EndCity only to find we're going in the wrong way and some people don't even know Endcities exist so these maps would be really useful but I think there should either only be one EndRuin or only the first EndRuin you find would have a map in it. There should also be unique mobs guarding them like EndGolems or guards.
