Land of Lost Souls

When you die on the Hardcore League server, your character is permanently (until the end of the season) transferred to the Land of Lost Souls.

During the season
There's not much that you can do at this point. This area does not come with any amenities (shop, banker, ...) or exits.

One notable thing you can do is Guild management. For example, if you're the guild leader, you can resign, so that you can transfer the character off the server (guild leaders cannot transfer servers).

After the season
Once the season is over, a swirling portal appears on the floor that leads back to the land of living (more precisely, to the Marketplace). You can reaccess your mail and bank. Your available actions are still quite limited; see wrap up.
