Lords of Creation: Ancients of the Void
The Reticulum refers generally to the network between minds enabled by the Incunabula, and more specifically to the Hive Mind which arose from this network. The Skree, the original members of the Reticulum, know nothing else and have little individuality. They are so subsumed by the connection between each other that in practice speaking with a Skree is equivalent to speaking with all of the Skree.
Towards the end of 2 DSC, a small number of Skizzik were invited to join with the Reticulum. They are likewise mentally connected to all other members of the network, but because they have experienced a lifetime of individuality they rarely become part of the Hive Mind, although it is possible. During the initiation, known as the Ritual of Melding, their arms are replaced by a type of living metal derived from Scarto’s accretion sphere.
