The Sky Sanctums · Date a Slime

The sky sanctums are the lairs of the Spirits: seven giant islands, one per Spirit, floating at the very top of the sky, their summit brushing the build limit. They are very rare, no path leads down to the ground, and at the centre of each arena sleeps a Spirit who wakes when you arrive — and comes back three hours after her defeat.

Generation

Where: in every Overworld biome, regardless of terrain: the island floats at a fixed height, its base at Y 214 (Origami, Mukuro, Kurumi) or Y 222 (the other four), its top at Y 318.
Rarity: each sanctum has its own grid. For Origami, Mukuro and Kurumi, one per square of 320 chunks (5,120 blocks), at least 160 chunks (2,560 blocks) between two of the same Spirit. For Nia, Yoshino, Natsumi and Miku, one per square of 352 chunks (5,632 blocks), at least 176 chunks (2,816 blocks) apart. The seven grids are independent.
No monsters spawn inside them, and nothing leads down to the ground: no stairs, no ladder. Get up by flying, building or with ender pearls.

The Spirit and her marker

At the centre of each arena, an invisible marker (dateaslime:spirit_sanctum) watches over the Spirit:

it calls her ten seconds after the area loads ("Spirit awakens in her sanctum.", for players within 96 blocks);
it remembers the last time it saw her alive and calls her back 180 minutes later — game time, server running. Set with the spiritRespawnMinutes gamerule (0 = never);
the leash: if the Spirit strays more than 72 blocks away, or falls more than 24 blocks below the arena, she is brought back to the centre. You cannot beat a Spirit by pushing her into the void;
there are never two Spirits: an old one coming back after her replacement is sent away.

An operator can place a marker by hand, with Spirit = origami, mukuro, kurumi, nia, yoshino, natsumi or miku:

txt

/summon dateaslime:spirit_sanctum ~ ~ ~ {Spirit:"nia"}

Commands

txt

/locate structure dateaslime:nia_sanctum
/place structure dateaslime:nia_sanctum

Replace nia with the Spirit you want. /place generates the sanctum at your horizontal position, at its usual height in the sky.

The seven sanctums

A white quartz citadel. A 75-block arena stamped with a gold and blue rose window; eight of Metatron's feather cannons standing on bastions — one of them blackened; a golden halo floating 31 blocks above, linked to the cannons; arcades and a crystal keel under the island, and four islets around it.

An indigo lock plate pierced by a golden keyhole, marked with a twinkling four-pointed star.

A concert hall.

Tips

Look up while exploring: the keels, towers and Natsumi's witch hat hang or point well above the clouds.
Plan the climb and the way back down: the island starts above Y 214, often 150 blocks or more above the ground.
The chests are the real reward: the Spirits themselves only drop experience and, one time in a hundred, their Qlipha Crystal.
The chests only fill once; the Spirit, however, comes back.
