Part 7 starts at the bottom of a wind shaft in the white wool dungeon. The party is still Basket, johnfal_92 and Dash (dash10138), going by the nameplates and chat, and Scoti isn't on. Getting up should be the easy part. It isn't.
Riding the wind
The winds work, sort of. Someone shoots up, someone else gets halfway and drops right back down, and archers keep firing at whoever is waiting. "I don't know how to start the process of flying." Dash whispers a tip about walking on the rails, which leads to some confused hopping on iron bars. One of them reaches the top by going off to the side and pillaring up. In the end the trick is simple. "You just walk off the side."
Three shrines
At the top is a long sign. The chambers ahead lead straight to the God of Wind, but it's perilous. Inside the chambers are also three shrines that will protect and heal them when they meet Quetzalcoatl, and each shrine will spawn a potion spawner in the final battle.
Dash keeps count in a whisper: the first lot of three things, the second lot of two, and now three more. So the boss isn't next. First they find three shrines, maybe one in each direction. They sort gear into chests, money in the top one, then everything else, then armor, and head right.
A room worth keeping
The right wing has creepers overhead, a big mob with a big sword, and lava under a floor only one block thick. There's a jaguar spawner up top and archers across the way. One room has at least four spawners in it, and instead of breaking them all, they decide to keep it as a grinder for later. A couple of chests get noted for the return trip, one of them probably trapped.
The Totem of Bones
Further on is a lava room with blaze spawners and a ghast spawner up on a tall pillar in the middle. Gravel on the floor means somebody already set off a trap. "You're activating a ghast spawner, Basket, just to let you know." Dash digs through a wall to get at a blaze spawner, the ghast spawner goes down, and behind it all is a button on an obsidian floor with a sign reading The Totem of Bones. They press it. The Totem of Bones has granted you a boon. Use it well. One shrine down.
A priest and a pile of arrows
The next stretch costs johnfal_92 a life. The chat line reads: johnfal_92 was slain by Quetzal Priest. The complaint afterward is about not having blocks to get away. A creeper waits by the dropped gear, so the pickup takes some care.
Most of the mobs here are skeletons, so the arrows pile up. "I got tons of arrows." Dash takes out one more spawner, and they find a narrow path going down with water below, not lava. With time running short, they call it a decent spot to stop.
