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 ImperialNavy operations headquarters.
Helidus Secundus (Forge World): Standard Orbit, No Axial Tilt, Earth-like Gravity, Breathable Atmosphere (Type II: Breath Mask Suggested), 48% landmass, 52% water, Plain-Dominated Landscape (where bare land still exists)
Helion Prime (Hive World): Elliptical Orbit, No Axial Tilt, Heavy Gravity, Breathable Atmosphere (Type II: Breath Mask Suggested), 52% landmass, 48% water, Mountainous Landscape (where bare land still exists)

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 seventy years of slave labor without trial.
Spire Romellus, home of House Romellus and the seat of the Helonian monarchy.

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 a 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.
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.
