Communication Lacrima

A communication lacrima is a type of spell lacrima commonly used throughout Atria. There are a few different kinds to suit different needs. Communication lacrima typically function by tapping into a network produced by another lacrima. By using either magitech mechanisms or being directed by a knowledgeable wizard, it can connect with another, specific comm lacrima on the same network.

Full-sized
The most common type of comm lacrima is the full-sized variety, which typically takes the form of a clear crystal ball. It can project whatever image is reflected on its surface to the lacrima it is communicating with. Most full-sized comm lacrima sold in shops and set up for public use are all connected to the same nation-wide network maintained from the capital.

These lacrima are also a key component in a new magitech invention known as the television. As they are still quite rare, there isn't a network meant for them of the same size as the main communication network. They are usually linked to surveillance networks used and maintained by wealthy individuals.

Audio
This type of communication lacrima can be made smaller than the full-size, and is a key component in radios. It otherwise works the same. In the past it was primarily used for contacting other people, but has since been replaced by the full-sized communication lacrima for that purpose.

Miniature
A recent invention, the miniature comm lacrima takes the form of a pearl-like crystal that can easily fit in one's pocket. Some choose to attach it to an earring or other earpiece for hands-free access. This type is much more limited in its use than the full-size, as not only does it not project an image but it is also too small to properly enchant in a way that can connect to a full network.

There are a small number of miniature comm lacrima capable of this that have been created using high quality lacrima crystal, but most are instead designed to link directly with a small number of other communication lacrima that are created at the same time. They are popular with small teams of guild wizards to stay in contact when splitting up during a job. Attempts are still being made to apply them to magitech without sacrificing the benefits of their size.
