Great House Auriverde

The  is an ancient and powerful noble family hailing from the world of Ianuarii in the Ember Sector's Santacruz Sub-sector in the Segmentum Tempestus. Prior to their integration into the Imperium of Man, the family was known as the Royal House of Auriverde and ruled the Santacruz Empire in the Ember Sector. Following a short war with one of the Imperium's Expeditionary Fleets, the family surrendered their crown to the Emperor and swore eternal loyalty to him and his Imperium. For this, they were allowed to keep their rule over the newly founded Ember Sector as Lord Sectors in the Imperium's stead.

 * Pedro the Magnanimous: The mythical founder of the house. He is most known for having unified the many worlds of the Ianuarii System under his control. It is in his honour that every patriarch of the family takes the name Pedro upon ascending to the role. The cross that is used on the family's crest also came into use with him and according to legend it is a symbol that can be traced back to the Holy Terra itself.

House Lima
House Lima is an Imperial Knight House which has strong ties to the Imperium as a part of the Questor Imperialis. House Lima hails from the Segmentum Tempestus's Ember Sector, more specifically the Santacruz Sub-sector. When the region was independent, before the Great Crusade, the house owed allegiance to the Great House Auriverde. When the sector was brought into the Imperium, House Lima was made to answer directly to the Imperium of Man's Questor Imperialis. Nonetheless, House Lima has still maintained close ties with their former lords. Enough so that members of the Great House had married into the Knightly House.

Thunder Skulls
The Thunder Skulls are a mostly Codex Astartes-compliant Loyalist Chapter of Space Marines and a Successor Chapter of the Silver Skulls, itself supposedly a Successor Chapter of the Ultramarines of the Second Founding. It was founded in 978.M37 during the 23th "Sentinel" Founding following a vision witnessed by the Chief Prognosticator of the Silver Skulls, who prophesied that the Segmentum Tempestus would face a major threat and convinced Lord Commander Argentius to send the entire 5th Company to garrison the region preemptively as a new chapter with the permission of the High Lords of Terra. The vision proved to be true as in 113.M38 the Black Crusade of Von Mallas erupted in the Segmentum Pacificus and soon spread to the Segmentus Tempestus. By the time that the Black Crusade came, the Thunder Skulls had already been dealing with local instability in the region for over a century and had established strong roots in the Santacruz sub-sector, where they are known to the locals as "Caveiras".
