janqualia block

A luminous return portal that leads back to the main world, Naraka. It drops when broken. It can be made through Apotheosis, and it also appears as a placed block in three places:

1. One spawns by default inside your clonaqualia block world, so you can return to Naraka after entering it.
2. The Firmament — a grid of grass blocks over a void (snow falls here), reached by touching a Dominion.
3. In Alma, the plaster-walled "backrooms" dungeon reached through a vismruqualia block, it spawns very rarely and far apart. Don't count on finding one before you go in.

"I found only two Janqualias after searching a total of 12,000 blocks in various directions." — @ImpossibleEvan

Once obtained, it can be placed and reused as a portable exit — unless you are already in Naraka, a challenge arena, or the YHVH dimension, the last two of which cannot be left through qualia portals.

Through Apotheosis, the Janqualia block is most easily obtained by combining clonaqualia block with almost any common block (including plaster block).
