Thor

-Largely owned and presided over by the Mechanicus.

-This Spire's population has a specific and notable phenotype of dark hair and pallid skin that has been noted in the victims of exsanguination. Investigations of the clinics in this Spire have also yielded results showing still living individuals with inert particles in their bloodstreams.

-Near a concentration of this particular phenotype, a member of the Asterion Arbites was assaulted by individuals likely to be agents of Lady von Tarquinius. The cause of this event has yet to be determined.
