You will arrive in the centre of the AvoVerse Lobby world, in a small house.
Follow the signs to skyblock which will lead you through the dense jungle to a platform. Stand on the pressure plate.
You will be teleported to the white Island. From there, head to the centre and when you get there, veer left and head towards the planet in the distance.
At the end of the road, stand on the pressure plate to be transported to the planet which acts as the interdimensional portal to Galactic Skyblock SMP.
Once there, walk through the gateway with 3 pressure plates and it will instantly transport you to the Spawn System, where you can start your Galactic Skyblock Journey.
