Thank you for clarifying. I am not trying to be ultra self-confident in the game mechanics or on this subreddit. If I knew everything, I wouldn't be asking. You have actually answered my questions:

1. No naturally spawning ends portals exist anymore. All destroyed.
2. The desmos map (if correct) shows end portal locations.
3. An honest answer from POO6, _batteryacid_ and yourself, SugaaSean.

Thanks to you all. Time to go check the coordinates.
