High Fabricator Castellar

At the apex of authority for the Adeptus Mechanicus in the
Calixis Sector is a singular title: the High Fabricator of the Lathes. Currently, Arch-Magos Castellar holds this position.
A well-respected Arch-Magos who ascended to his current
title through diligence and shrewd political maneuvering,
he took over from the disgraced High Fabricator Garamond.
However, during his lengthy tenure as High Fabricator,
Castellar has grown increasingly aloof and detached from
the Mechanicus interests within the Calixis Sector, preferring
to focus on the Explorator fleets and expansion through the
Koronus Passage. It is commonly suspected that Castellar,
a former daring Explorator himself, has distinct leanings
towards the somewhat radical beliefs of the Disciples of Thule. Whatever the truth, Castellar’s vision seems to be
firmly fixed beyond the concerns of the Calixian Mechanicus
and directed towards exterior operations.
One of the High Fabricator’s accomplishments include
the establishment of a sophisticated network of vox-heralds
throughout the forge worlds of the Sector, and in many
important Imperial planets as well, such as Scintilla, Malfi,
and Sepheris Secundus. It is known that he is quite sympathetic towards the warlike Divine Light of Sollex sect.
Chrono-gladiators are another particular interest of
Castellar’s, and it is he who helped establish the great slaughter-wheels
of Hive Volg. The High Fabricator selects a new cadre of
bodyguards from the champions of the Chrono-gladiators every
decade. These matchless warriors serve with fanatical loyalty,
due in no small part to the knowledge that the High Fabricator’s
continued function is tied directly into the life-timers of each
Chrono-gladiator. Nominally, these timers are kept stilled as a
reward for the Chrono-gladiators’ service. However, should the
High Fabricator come to any harm, his bodyguards soon see
their lifespans measured in a handful of seconds.
