Went through the House Arano sourcebook and updated the canon_systems files to match. ChangeLog:

Named Moons
Coromodir VI, Guldra, Itrom, Panzyr all have named moons that have been added

Artru
(p. 35): "a barren, icy rock with almost nothing of value... too dangerous for permanent habitation, crews only stay for month-long shifts, before returning to one of the orbital habitation stations."
temperature: 20 -> -20; water: 79 -> 0; lifeForm: BIRDS -> NONE

Bringdam
(p. 35): "A lush, high-gravity world, Bringdam's atmosphere is so dense as to be almost unbreathable."
pressure: THIN -> HIGH

Fjaldr
(p. 35): "a bleak ice planet, swept constantly by howling winds and blowing snow. The original Confederation colony was largely underground..."
temperature: 20 -> -51; water: 33 -> 0

Heliat
(p. 32) Surface Gravity: 1.2 -> 1.3

Ichlangis
(p. 35): "a Mars-like planet with an atmosphere too thin to breathe, no surface water, and temperatures below freezing. The planet is rich in titanium..."
pressure: STANDARD -> THIN; water: 38 -> 0; temperature: 32 -> -60

Mangzhangdian
(p. 35): "marginal pastoral world"
water: 100 -> 85

Qalzi
(p. 35): "The cold and rocky world is technically in legal limbo..."
temperature: 44 -> 6

Ryan's Fate
(p. 35): "hot, arid world with a single, shallow, briny sea"
water: 41 -> 21

Smithon
(p. 34): "The lack of moons has left the planet with a day lasting only sixteen hours, making it extremely disorienting for the surface population."
dayLength: 21 -> 16

Umgard
(p. 35): "Due to the tidal stresses of Umgard's two moons, the planet is torn by volcanoes and earthquakes..."
smallMoons: NULL -> 2

Zangul
(p. 35): "a cold water-world with chains of rocky islands and sprawling archipelagos."
temperature: 35 -> 4; water: 44 -> 84

pg. 32 of House Arano - The Aurigan Coalition [2019]  notes the gravity is 1.3 not 1.2.
pg. 34 of House Arano - The Aurigan Coalition[2019] "The lack of moons has left the planet with a day lasting only sixteen hours, making it extremely disorienting for the surface population."
pg. 31 House Arano - The Aurigan Coalition [2019] lists the moons.
Reviewed all the systems mentioned in the House Arano sourcebook and updated canon_systems files to match.

Obviously plenty of subjective interpretation here, happy to change anything.

Some questions that came up:

  • satellite size & icon - any guidelines?
  • Panzyr has orbital debris ring, how to add?
  • Tyrlon has rings, too
  • Frozen planets have 0 water, yes?

Added three key events from the House Arano sourcebook that might spillover into international news of interest to a merc.
Normalized all "pressure: Low" to "pressure: LOW" and "pressure: Vacuum" to "pressure: VACUUM" to be consistent. Dunno if these are case-sensitive fields, but the inconsistency bugged me :)

The best bet to lots of these is guess. Except for Frozen water, that is still expressed as water.

Per Hammer, I need to go back and re-do the frozen planets. Will do asap.

Adjusted water to reflect "icy rock" description, and massively reduced population to a "token staff" that rotates between the planet and the hab stations.

Adjusted Water to reflect an "ice-enveloped world".

I'm going to punt on adjusting satellite sizes and icons and debris rings for now. Water for ice worlds has been adjusted. Ready to merge.
