The signs in the hub point two ways. Deathshade Ruins, Em:23-24, goes one way. The Solar Citadel, Em:25-26, goes the other. "We need the Solar Citadel," and since they're out of things to do at the intersection, they figure there are probably two wools over there, or at least the way to the next area.
Out in space
The Solar Citadel is in space. There's a giant orange sun, planets with rings around them, and stars everywhere. "Oh my wow. It's a sun-splosion."
They start inside one of the planets. There's a chest, a hole you can jump through, and obsidian down below. "I'm inside the emerald planet. Something tells me this could be a trap." Underneath it there's only wood, ladders and bookshelves. They guess there might be an emerald up in the greenish planet, but the main objective is probably inside the sun.
Building the bridge
The only way over is to build. "Alright, I'm gonna start bridging. Cover me, man." Torches go down along the way, and they both expect ghasts and blazes. "Oh trust me, I'll know when they're here."
A bow guy shows up first, from a spawner, so more are coming. "Make sure you put something behind you, 'cause there's a big drop." "Safety third."
Friendly fire happens too. "Did you just shoot me?" "Yeah, I was trying to shoot over you. And then you got up." One of them is using Infinity flame arrows, which turn out to be hard to see through.
The center of the earth
Inside the sun there are lava spires in the middle of the room and blazes on the far left. A spawner goes down. Then one of them falls in a hole and gets beaten up down there, with a bow guy joining in. There are three ways out of that room.
The magma cubes are the real problem here, because they knock you right off a bridge. "There's a bunch of different dudes that can knock you off." Two more spawners go down. Partway through, Scoti's connection drops, and the chat shows them leaving and rejoining the game a few times.
Down to goblin town
Below that there's a blaze spawner and a big pit. "It goes down, down, down more." "Goblin town?" "Down, down, down to goblin town, yes." One of them finds out they have fire protection gear, which helps.
The next room is worse. Creepers fall from somewhere above, and the charged creepers seem to come out of a protected spawner in the middle. "Charged creepers! I'm out. Peace out." Then they spot mobs riding blazes. "Oh, there's dudes riding blazes. Oh, that's exciting." One of those drops a bow.
A torch run
So it's a torch run. "Put some torches down!" One of them gets all the way in to the charged creeper spawner, then has to pick their water back up after putting themselves out. There's a chest down there, and they guess the thing they want is inside the core.
The episode ends on a quick status check. "So, how lit up is the charged creeper spawner?" "I would say not very." Then: "Is this the end of the episode?" "Yeah! See you guys next time."
