This server is called Entrapped and it is a hardcore Attack on Titan lore world. Humanity is stuck inside walls and death is permanent so every choice you make really matters a lot.

The server follows the Attack on Titan story in order and events happen like the canon timeline until players change them by surviving or failing. There is no teleportation so traveling is slow and scary. Horses are super important because you train them and ride them into combat and on expeditions.

Outside the walls if you die it is over. The server has a Humanity Supply System that tracks food materials and other stuff people need to live. Supplies can run out so players have to go on expeditions farm and hunt or everyone is in trouble.

You get stronger by killing titans doing missions and going on expeditions. This unlocks passive abilities and specializations. The economy actually matters because money lets you buy gear weapons property organizations and your own private missions.

Wall defense fights titan outbreaks and training events are all permadeath so you cannot just rush in and be dumb. Titans stick around and surviving is never guaranteed.

The community is closed and they are looking for serious players who want a high stakes story and are okay with waiting for waves of access. If you like hardcore lore servers this is built for you.
