Basket builds the front gate of the keep at Basket Castle, with a stand-in portcullis and trapdoors overhead, then closes in the first floor and digs stairs down toward a basement.
A floor full of creeper spawners, a few charged creepers, a new axe for Basket, and a plan to drop sand and water down through the glass to reach an emerald.
Basket adds Projectile Protection to a chestplate that can't come off, Laminar Labs is full of skeleton, witch and blaze spawners, and breaking one window lets the water out.
Basket builds out the throne room in the keep at Basket Castle: layered standing room, birch pillars, a birch ceiling and a balcony, plus a test that proves doors won't stack.
An Enderman, a burning coal ghost, a record with Fire Aspect, spawners hiding behind beams, and an emerald frozen in the ice at the bottom of the mine.
Emerald 6 turns up behind the only cracked brick in the dungeon, Chillblast Mines is full of hidden spawners, Scoti meets a creeper, and a second emerald sits in a glass case.
Basket finishes the road around the keep's outline, plans grates for a future sewer, lights up a hole full of zombies, then blocks out the keep's gate towers, stairways and throne room.
Basket finishes the royal stables at Basket Castle, tries a birch outline and then dark oak stripes on the roof, and marks out where the keep will stand.
Basket lays out the Basket Castle stables, tests a stall by riding a donkey in and out of it, builds a row of stalls against the wall and fills the loft with hay and secret doors.
