Mizarin Tree Talking

If the lightwalker wanted to speak with you, you would understand its message

— Mizarin Priest

A form of communication that has for a long time baffled outsiders is how the Mizarin Nightlights communicate with eachother and other beings. It is, however, known to be possible as the Mizarin Priesthood has found a way to communicate with the plants. This allows them to command the trees to change their structure forming buildings in the process.
This communication is vital to the culture of the Nekorians but remains a complete mystery to outsiders. Even more curious is that the average Nekorian does not how to talk to the Mizarin Nightlight. Only the Priesthood has this knowledge and they don't want to share it.

The knowledge in this article is almost in its entirety not know to the general population of Niorath. For ease of access during summercamp I have made this available to all but this will later be limited to the Asmer Initiates group to keep the mystery for those who don't want to know more than the people of Niorath could know.

Communication

Light

One of the methods that Mizarin Nightlights communicate is by uses flashes of light. This is a behaviour only seen in the 'seeds' of the Mizarin Nightlights, known as the lightwalkers. They consist mostly of vines but they also have several light emitting globes with the largest one being at the top of their body.
The light from these globes can be used as a defense mechanism to blind attackers, but it is also used as a language between lightwalkers. Some outsiders have correctly deduced that short and long flashes of light in either fast or slow succession can mean different words. A few Nekorians that don't belong to the priesthood know simple words such as "Thanks" and "Water" but many don't bother to learn to identify the flashes.
When they "talk" to other species the lightwalkers tend to slow down their flashes in order for others to try to understand them. When talking to eachother they use flashes at astonishing speed and can communicate with eacother quite efficiently that way.

Mind Talking

The younger lightwalkers are not very proficient in talking directly to another being's mind. This is in most cases something that develops much later in their lifecycle. Nonetheless the Mizarin Priesthood is able to talk with both the lightwalkers and the older Mizarin Nightlights using something they refer to as the Holy Link.
It is a piece of technology that looks like a metalic band with protrusions near the front and actually originates from before the God War. When placed on one's head the area around the temples lights up with a blue light. Only by using this type of device is the priesthood able to talk to the Mizarin Nightlights. This is the method that the Mizarin Priesthood uses to issue commands to the nightlights.

Long distance

Unknown to even many of the priests the Mizarin Nightlights are able to use this mine talk with eachother over enormous distances. Many nightlights are able to communicate with any other nightlight on the planet almost instantaneously. The larger the Mizarin Nightlight is the further it can reach.
The largest tree, known as the Mothertree, is actually located on the largest moon, Naelik. It was placed there inside a large biodome by the Prime Asmer to function as a sort of relay station. The Mothertree is the only Mizarin Nightlight capable of contacting the nebula of Nervonia. All communication of the Prime Asmer Gods therefore actually goes through the Mothertree.

Origin

The plant from which the Mizarin Nightlights were created was actually discovered on another planet by the ancestors of the Beastfolk, Gnomes and Halflings. After succesful genetic engineering they were able to increase the range from a few metres to vast distances, allowing almost instant communication between planets.
When they arrived on Niorath the brought the enhanced Mizarin Nightlights with them and used it for communication once more. When the more advanced Prime Asmer arrived they saw the potential and continued its use.
