Nullflower

Nullflower by Mochi

Nullflowers exist only in the Silent Halls. Or, they would, if they existed. There is no proof of their existence, only the accounts of those that made it out of the Silent Halls alive, of which there is just a handful.

According to these survivors, nullflowers are a bright blue and grow in the forests of the Halls. They are intangible, unaffected by the breeze or any weather, completely immovable even when walked into. In order to preserve the flowers, physical matter is destroyed and reformed around the flowers.

Still, it is entirely possible they do not exist. The Silent Halls is known to warp the minds of those that are trapped there, creating false realities and living nightmares. Things in the Silent Halls exist nowhere else in the Yonderverse, and it is better that way.
