Dholen is turning into a red giant. As the star matures, the system experiences magnetic eruptions and increased solar output. This is a gateway system, although it has no fuel depot.
Because this is a geth-controlled system, all civilian traffic is prohibited. Resource estimates are moderate to rich.

Gotha:
- Orbital Distance: 1.5 AU
- Orbital Period: 1.8 Earth-years
- Keplerian Ratio: 1.042
- Radius: 1,056 km
- Day Length: 66.4 Earth-hours
- Atmospheric Pressure: 99.64 atm
- Surface Temp: 590 °C
- Surface Gravity: 0.1 g
- Mass: 0.003 Earth-masses
A dwarf planet, Gotha has a pressure-cooker atmosphere that brings its surface temperature to a scorching level. Carbon dioxide and ethane are plentiful in the planet’s hazy atmosphere.
There has been speculation in the mining community about whether all of the precious metals were mined by the quarians before they fled the system some three centuries ago. Rumors abound that anyone who could brave the geth in the system could find lodes of naturally occurring diamonds on Gotha, but this is likely just a starship legend.
TRAVEL ADVISORY: Gotha is in geth space. All civilian traffic is prohibited.

Charoum:
- Orbital Distance: 2.9 AU
- Orbital Period: 4.9 Earth-years
- Keplerian Ratio: 1.016
- Radius: 54,532 km
- Day Length: 11.3 Earth-hours
- Atmospheric Pressure: 1.37 atm
- Surface Temp: N/A °C
- Surface Gravity: N/A g
- Mass: N/A Earth-masses
- Satellites: >1
- Colony: Geth
Capital: none, founded 1895, population 250,000 to 500,000 platforms (A.I. constructs/robots)
Once a starship refueling station for the quarians, Charoum has expanded under geth rule. Thousands of orbital platforms surround the planet and its many moons, refining helium into helium-3. A vast geth fleet comes and goes between Charoum and Haestrom, preventing all but the most stealthy of spy drones from discovering any information about it. Current estimates place the geth fleet numbers between 5,000 and 10,000 ships, with unknown levels of armament.
TRAVEL ADVISORY: Most intelligence estimates state that approaching Charoum is tantamount to suicide. All civilian traffic is prohibited.

Quarian Envoy Ship:
This diplomatic frigate is like no quarian ship on record. Its hull is relatively low temperature and it appears to be venting heat in a manner similar to that of the Normandy when it comes out of stealth mode. How the quarians developed this high-tech vessel is unknown, but its hailing frequencies are open and welcoming messages are being tight-beamed to the Normandy.

Haestrom:
- Orbital Distance: 6.3 AU
- Orbital Period: 15.8 Earth-years
- Keplerian Ratio: 1.002
- Radius: 6,721 km
- Day Length: 18.5 Earth-hours
- Atmospheric Pressure: N/A atm
- Surface Temp: 44 °C
- Surface Gravity: 1.2 g
- Mass: 1.323 Earth-masses
Formerly a quarian colony, Haestrom was established to observe the phenomena on Dholen, the system’s parent star. Dholen appeared to be unstable with a high possibility of erupting prematurely into a red giant.
Haestrom was lost to the geth in 1896 CE. Soon after, all communication from the planet and its attendant space stations ceased. The geth have shown no signs of treating Dholen as a threat over the past three centuries other than establishing several space stations near it. Dholen’s magnetic eruptions and solar output overwhelm most communications near it, and it is unclear how the geth have compensated.
Today, spy probe scans indicate extensive orbital construction around Haestrom, housing thousands of geth platforms and an unknown number of geth software “minds.” It is not known how many geth are on the planet’s surface: spy probes face interference from Dholen, making remote scanning difficult. Resource estimations based on geth mining, refining, and fabricating practices suggest that the planet has at least 20 more years of use before it is exhausted. Intelligence experts speculate that the geth have not exploited all of their resources because they wish to keep some in reserve for repairs.
TRAVEL ADVISORY: Haestrom is a geth stronghold. Military spy drones using cutting-edge stealth technology are the only vehicles that have returned unharmed from geth space. All civilian traffic is prohibited.
Codex Entry
Before the geth revolt 300 years ago, the quarians colonized Haestrom to study the mysterious instability of its sun, which threatened premature eruption into a red giant. As a scientific outpost of minimal military value, Haestrom was ill-equipped to repel geth forces during the insurrection and fell quickly under their control.
Captured geth planetary survey data indicates that despite sustaining damage, Haestrom’s architecture remains as it was before the war, preserving a quarian architectural style that no longer exists anywhere else in the galaxy.
Because Haestrom’s sun has overwhelmed the planet’s protective magnetosphere, humans foolhardy enough to venture into geth-controlled Haestrom must exercise extreme caution. Minutes of radiation exposure will overload shields and hours of exposure will kill. Furthermore, solar output renders surface-to-orbit communication nearly impossible.
