Helianthus SMP Season 2 is a survival world that is built to last a long time and not just be a quick phase. Progress is slower on purpose and the server is more punishing so you really need to play together with other people.
Everyone joins one of three Houses. Adamant is the industrial and mining style House. Demeter is the nature and farming House that feels kind of communistic. Theurgy is the magic style House with greedy warlocks and explorers. These Houses are led by players and they shape how the server works.
The world has three difficulty stages. At the start it is Normal and surviving is hard but possible if you stay with your House. When the first player enters the Nether the world changes to Hard and creatures get tougher. When someone reaches the End it goes to Extreme and late game becomes super wild but by then players are already strong.
There is a custom role play system with Houses and even monopolies. Your choices can change the structure of the server and the power of your House. There are relics trade wars and territory struggles. Resources in the world are limited so you have to decide if you want to dominate negotiate or trade with others instead of just grinding alone.
