Helidus System

This article, Helidus System, was written by Anonymous ONI agent. Please do not edit or 'acquire' this fiction without the writer's permission.

The Helidus System is a star system located in the Ultima Segmentum, in Subsector Xitalis of Sector Auvidus. The system orbits Helidus, an F-class white star, and is notable for its large number of inhabited planets and moons, as well as for Fortress Markalus, a major Imperial Navy operations headquarters.

Helidus Secundus

Lord-Fabricator Maxentius Eugenium, governor of Helidus Secundus circa 999.M41.

Warlord-class Titan Sword of the Omnissiah during its only recorded operational usage during the invasion by WAAAGH! Lead 'Ead in early M37. For his valiant service during the conflict, the Titan's Princeps, Karl Schrafft, was canonized as a minor saint of the Cult Mechanicus by the Fabricator-General of Mars at the time.

Helion Prime

Helion Prime as seen from orbit, with Ephelion Station visible in the foreground.

Grand Baron Ichvalde Helmuth Klaus-Romellus XIV, governor and monarch of Helion Prime circa 999.M41. Ichvalde is the most liberal Grand Baron Helion Prime has seen in centuries, especially considering his radical decision to change the penalty for publicly speaking out against the monarchy from execution on sight to ten years of slave labor.

Spire Romellus, home of House Romellus and the seat of the Helonian monarchy.

Aerial pict-capture of a seaside hive, taken from the planet's lower thermosphere.

Pict-capture of the Administratum district on Spire Romellus.

The greenskin hordes of WAAAGH! Lead 'Ead wrought havoc on Helion Prime in particular when they attacked the whole of the Helidus System in the early 37^th Millennium.

Spire Vetrius burns at the hands of WAAAGH! Lead 'Ead. The spire would later collapse into the sea, and the area remains closed off to this day.

Pict-capture of a spire's lower industrial district. On Helion Prime, this level tends to be the highest level on which mutants are permitted to venture out in public.

Stryfe's Heart

Oryntius, the capital of Stryfe's Heart, as well as the planet's largest city.

Helidonus Minor

A pict-capture that many believe was taken within a hidden altar on Helidonus Minor.

Fortress Markalus

Admiral Ulrich von Straussmachten, chief commanding officer aboard Fortress Markalus circa 999.M41.

Crecaelia

The southern walls of Cornelius Point, the largest and most important land-based military installation in the entire system. Cornelius Point is home to nearly three million Astra Militarum personnel.

A famous pict-capture taken by Imperial remembrancer Heinrich Sturgent during the invasion by WAAAGH! Lead 'Ead in M37, titled "The Unyielding Gates of Crecaelia". The main gate of Cornelius Point has been known as "The Unyielding Gate" ever since.

Trivia

• The Helidus System was first created during the summer of 2014 using a set of random star system generation rolling tables, and it took about four straight hours to roll up. It then sat on Anon's sandbox wiki for about two years before finally being published here in June 2016.
