I found a modded Minecraft SMP that is growing fast and it is trying to get new people in early while the world is still pretty fresh.
The server has deep lore and it is heading into season 2 with a big fantasy theme. The story is about dragons and monsters and the land is supposed to be full of them. With the Ice and Fire mod you can search for dragons fight them and even tame your own.
You can play as a monarch running a kingdom or be a warrior or just be a tavernkeep. There are also other monsters plus custom structures and dungeons to explore.
The world border is kept smaller so players stay closer together then it expands over time. People are encouraged to form settlements and player houses. PVP is allowed but random killing is not the vibe and wars are meant to be more formal.
The server uses a whitelist so you have to apply first.
