This is a server using the All The Mods 9 modpack and it is planned to run until the end of March and maybe longer. It feels like a chill place to play survival with lots of tech and magic mods.
Some big mods on here are Create Ad Astra Applied Energistics 2 Mekanism Mahou Tsukai and Blood Magic plus a bunch more. So you can build machines explore space do crazy magic and make big storage systems.
They use a land claim system so your base is mostly safe from griefing by other players. The owner clearly does not allow pirated accounts so you need a real Minecraft account to join.
There is also a tutorial that shows you how to get the mods working so even if you are new to modded Minecraft you can still figure it out and join. The server feels like it is aimed at people who want a long running modded survival world with other players.
