We have so many kinds of flowers in this world! Pretty flowers, angry flowers, hungry flowers, nosy flowers... The witnesses are the highest kind of nosy flowers. They listen to everything and never forget, but they are quite polite and don't go around talking about it. Not with words, not with their smell. Some s believe that they do share all kinds of secrets with each other, but never with other creatures... unless you nicely ask them to carry a memory for you, but that's not gossip, obviously.
And they are quite reliable to do so, always find the recipient and never share a single thought about it with anybody else. They do that freely, but not without a good reason.
|This ghost is usually formed by several shards related to relationships that ended by the things that were never told: terrible secrets found in the worst moment, loving words that the owner of what was lost didn't know how to tell, and more than anything: apologies that weren't to hard to say or didn't find the right time. Slightly less common, is to find witnesses formed by the shards of emotions that never become relationships because they were kept in secret.
They are one of the few types of ghosts where the shape and color are consistent between different specimens: always white, simple flowers, small enough to fit in a human hand. All of them look like flowering grass, but when you cut the flower, is the rest of the "plant" what dies after a while unless other shards gather around it to form a new flower. We don't cut them to decorate our hair or house, that would be an unnecessary risk when similar flowers grow in human settlements, or even materialize in the room we want to adorn. the reason why some of us adopt one or many of these creatures is to sent messages to distant places.
