Prime Interface Andrew de Lacy

Andrew is Prime Interface and Chief Programmer of the Nexus System, which was his brainchild. Son of King Robert of Sable, their close relationship means that Sable is a natural ally to the Technocracy, although the two worlds are very different, and there is little commerce between them. However, they do have a Mutual Defence Alliance for matters military and Andrew is personally influential within the Sable sphere of influence.

Niamh McCormick de Lacy

Niamh encountered the Technocracy before she actually first met the Prime Interface, in the period when the Master of the Machine was attempting to exert his influence on the Nexus. Andrew met her in Shadow, and helped her find herself again, and they married in April SY150. When he is away on his work for Sable, she acts as the Warden of the Primary Node, and runs Nexus Prime in his stead. She and Andrew have three children: Lucy, Abigail and Jonathan.

Sysdaemon Lucy

Lucy is the eldest of Andrew's and Niamh's three children, and also the most "otherworldly". Her link to the Nexus Datastream is second only to Andrew's. Most of her existence is within the Nexus, where she acts as its Keeper and Controller, although she does have an external avatar should she feel the need to venture out.

Secondary Interface Abigail,
Tertiary Interface Jonathan

Abigail and Jonathan are twins who were born and bred on Nexus Prime, and they both knew that their ultimate destiny was to be the Interfaces of the Secondary and Tertiary nodes. Initially Jonathan accepted this more willingly than his sister, but as they became more aware of the history of the Technocracy, and the early problems with the Master of the Machine, Abigail also accepted that what she was being asked to do was important.

Unlike Lucy, both Abigail and Jonathan (plus their half-sister Helena-Maria) are primarily human, although like their father and sister, they have an enhanced link with the data stream.

Quaternary Interface Helena-Maria

Helena-Maria is the child of a previous relationship Andrew had after the death of his first wife, but before he met Niamh. She has spent several years working with him in his military duties for Sable, and is a capable and able military commander in her own right. He invited her to become Quaternary Interface with the establishment of the Quaternary Array, out in the region of Shadow around New Oceania, in late-March SY155. As her loyalty is more to him than to Sable, she agreed readily.
