Just noticed that the current version of the Crystal Shrine structure has end portal blocks above the treasure room, which has a couple issues. First off, the underside of end portals doesn't always render properly (which is a vanilla issue), so the starry sky effect is lost if you look at the wrong angle (see screenshots, only thing changed between the two was where I looked at it from). Second off, going through that portal just teleported me into bedrock at the bottom of the Overworld.
I'd suggest replacing the end portal blocks with end gateway blocks, which use the same texture as the portal but should render better and be safer to teleport with, though teleports are confined within the end. I'd give the gateway blocks {Age:-9223372036854775808L,ExactTeleport:0,ExitPortal:{X:0,Y:0,Z:0}} for data, where the negative age should disable/delay the beacon beam, exact teleport is off to land the player on a safe block, and those coords to send them back to the main island.
