The newest entry in the Odd and Peculiar series of modpacks. Here there will always be something on the horizon to explore, and with trains (or would you prefer a dragon?) you can bring that horizon to you!
Still a sandbox game, you are free to create yourself, with an expanded build-palette, and you can build factories, giant crop-fields, and *checks notes* flesh contraptions???
You’ll be able to discover a magic of your own as well, some you are born with, some you learn, and some you die with.
If you would like to have your origin change whenever you die, such as in the X/After/New Life SMP, you can opt in to that feature, either by doing the command /function odnn3:chameleonred (if you would like a cooldown between changing origins, you can instead use chameleonyellow for a 4-hour cooldown or chameleongreen for 8 hours) at the location of the player you want to opt in, and opt out with chameleonnone, or you can seek out the Grandchameleon Monument in the world to devote yourself to one of the three chameleons (A more immersive way of opting in and out of this system)
Should things ever start to get a bit stale, you could always head to the DayMonth ~ Year of the launch of Minecraft's first spinoff game.
