Amber

Also called "Myelimalan Amber", "Azmozian Amber", or even "Domundian Amber" after its isles, continent, and World of origin, it represents one of the Eight Magics of Domundus.

Creation
A few rare species of plants indigenous to the Azmozian "Myelimala isles" contain a special kind of sap that, if left to harden, will turn into Myelimalan Amber in the span of about one Domundian year.

Use and properties
Lighting Myelimalan Amber on fire will cause it to start burning with a very slow, low-heat fire which produces a steady line of smoke that reaches up into the sky and does not dissipate or diffuse into the air, but rather acts like a rope or string reaching ever upward. This smoke is often called Skysmoke. Once the Skysmoke reaches high enough, it is said to “connect to the sky”, enabling communication between people separated by great distances who are both burning Amber and thinking of who they want to connect to. Communication happens in a sort of mind-to-mind way, being often described as telepathy or voices in one’s head, leading to the conclusion that Skysmoke is a telepathic conduit. Anyone tuching the Skysmoke can telepathically communicate with others who are doing the same.

A main property of Skysmoke is that the only thing it diffuses in is water, meaning that if it hits a cloud or dense enough fog, it will connect to it and diffuse into it, in essence creating a cloud of Skysmoke where everyone touching it can telepathically communicate with all others also touching it. This often becomes a problem during cloudy weather; if Skysmoke hits a cloud on its way up, it will not travel further past the cloud, and will connect to the cloud and stick to it, so burning amber during cloudy weather is often ineffective and just a waste of materials, unless the person one is trying to connect to can also connect to the same cloud, and they don’t mind anyone else in the vacinity listening in to the conversation if they connect to the same cloud.

During rainy weather, it is basically impossible to get Skysmoke to even the height of the clouds, as the rain eats away at it on its way down. This does indeed mean that the water becomes telepathic water, and also indeed means that connecting Skysmoke to a body of water connects them, making the water into a telepathic conduit.
