PHASE 6
As the system reaches its mature phase, the disruption caused by the outer planets continues to hurl water-rich bodies into the inner system.
Hunter3K inches outwards from the sun, at the same time as receiving a barrage of comet strikes. Dusty deserts and sparkling ore fields become completely flooded by water. Only the tallest mountain chains now rise above the waves. A highly magnetic core deflects radiation from the sun and creates spectacular auroras, but the new planetary ocean is loaded with dissolved metals and toxins. Nonetheless, pioneering microbes begin to slowly alter the chemistry of this ocean (microbial life).
The core of Spryverri cools off a little, but the thick atmosphere continues to trap heat. Despite being further from the sun, the surface is hotter than Hunter3K and poisonous seas exist at the poles only. The planet's high gravity continues to attract comets and asteroids. The sluggish continental plates have a smooth, multicoloured, eroded surface, dotted with salt lakes and occasional massive volcanic features (microbial life).
Citizen1 moves as close to the sun as it can without being fatally disrupted by Spryverri. It is not close enough to keep the planet warm. Volcanic activity slows as the core reaches a more mature phase, and the surface is almost completely frozen over. Occasionally, geysers are seen erupting from the muddy ice, and there is some cycling of liquid water through sub-surface geothermal systems (microbial life).
The upper cloudscape of Mergatayren is stained green by plumes of sun-loving microbes, floating above darker and denser layers of cloud where microbes specialise in heat-driven chemical reactions (advanced microbial life).
The mantle of TBG remains watery (microbial life).
The heavy object Ig collides with the unstable moon Badunoff, creating the Badig ring of irregular moonlets around Mergatayren (sterile).
Kalotherco moves inwards as the giant planets reach their final orbits. The small increase in heat from the sun makes little distance to the planet which is heated from within by gravitational friction and is also highly radioactive (sterile).
North is sent into a highly eccentric orbit after a near-miss with fellow moon Aikokidon, the latter being flung clear of Kalotherco's gravity and straight into the sun (Sun now contains: 0.1% Abaddon). Meanwhile the increased tidal forces cause greater strain on North, with the core almost reaching breaking point, but much more heat is liberated. Large parts of the surface now become liquid water on a regular basis, though deadly radiation keeps life confined to deep water, the extensive geothermal vents in particular (advanced microbial life).
Bestage remains cold and lonely, but safely distant from its bigger neighbours. Although rich in water, there is no layer where the temperature, pressure and chemical mixture allows life to take hold (sterile).
Cull is impacted by its large moon Luckymoose. The dramatic impact creates huge jets of material which may help to seed life across the rest of the system. It also changes the core and atmosphere of Cull, forging what is known as the new planet Lucule (66% Cull, 33% Luckymoose). Unfortunately the original microbial inhabitants of Luckymoose are not able to survive (sterile).
Omega survives in an unstable orbit, sprayed with countless tiny pieces of Luckymoose and heated by greater tidal forces, similar to North but not quite so rich in water and useful chemicals (microbial life).
Rendered just a little eccentric by the approach of Cull, the planet Lightfang gathers an ever-greater entourage of glittering moonlets, dancing and floating serenely along the outer edge of the system (sterile).
QUERY: Does anyone want to move to a life evolution game, simultaneous multi-cellular evolution on North and Mergatayren? Bonus powers would be awarded depending on what players did in the planet formation phase.
