Telimagic (Tell-e-magic)
Communication is an essential element of any organized body. Especially so for a nation, or collection of nations. Telimagic is exactly that. Magical telecommunication. Eternity's arcana consists of several tightly woven strands that spread out in every direction. Telimagic sends imagery, and audio through these strands, from the first telimagic orb, to the designated one. It consists of a three-foot pillar, runes along the top edge, and a one foot diameter crystal ball. It has changed Eternity for the better since its creation. Telimagic as a method of communication will only be improved, never replaced.
Utility
It is used as a form of communication to, and from the designated position, to anywhere else. Eternity's arcana consists of several tightly woven strands that spread out in every direction. Telimagic sends imagery, and audio through these strands, from the first telimagic orb, to the designated one.
Social Impact
It has improved the lives of many, as faster communication means less time before action can be taken against any problem. Laws are passed quicker, wars are won sooner, people can pay to connect with their loved ones over long distances.
Access & Availability
It is only available to the rich, or government bodies, as it is extremely hard to make.
Complexity
Its base function is pretty simple, the process of making it is the complex part, as several spells must be cast is a particular order. All these spells are hard to cast more than once per day, so each day you only get one chance.
Discovery
It was made in the nation of Brimbaria. The inventor was told of how a relative was dying, and by the time he arrived, they had already died. That was his driving force to develop this.
Related Species
This is a very clever way to mix magic and technology, Rathal was a genius.
I kind envisioned his as a sort of brimbarian Nicoli Tesla.
