janqualia block

A luminous return portal that leads back to the main world, Naraka. It drops when broken. It 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.

Once collected, 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.
