This is a Skyblock server where your islands never reset so it feels like you can keep building forever and keep expanding as you grow.
It has custom cave systems with multiple levels and the ores regenerate. There are also custom mobs and bosses down there so it is not just mining all day.
Fishing is a big deal here with over 100 unique textured fish to catch and collect plus 60 fishing mobs to fight.
There are hundreds of quests so you always have something to do. It also has seasonal payouts so you can compete hard or just play casual and still fit in.
Your progress is profile based so if you get bored of one island you can start a new profile and swap back anytime. They are also recruiting staff so joining early and being active matters.
Runs on 1.21+ with 1.21.10 native support.
