I found Taerel Network and it feels like a dark fantasy survival server with its own custom modpacks. Each server has different modded biomes so the world can look alien and kind of creepy.
They have lore about finding a sealed gate and stepping into a place with stone portals under an azure sky. The first area is a small settlement with a copper roof hall and a little tower by a lake. Past the lantern light it gets dangerous and strange things move in the dark so it really pushes exploring with friends.
The server is focused on survival and exploration and the world has no resets so your progress stays. Staff are said to be friendly and active and the owner is around and ready to help.
It is whitelisted so you have to contact the owner to get approved before you can join.
