Mars

''Out beyond Mars' Hill Sphere, a massive collection of Aneph and Arendelle ships drop out of warp, their combined power having been used to pull another comet out of the Oort Cloud and onto a collision course with the Red Planet. The comet, a whopping 36km in diameter, is released by the ships and allowed to gain speed as it heads towards impact in the Arabia Quadrangle. Several hours later, it passes near the Aneph Artificial Moon. which temporarily redirects its efforts away from producing tidal forces on Mars and focuses its massive gravitational banks on the comet, breaking it into a total of five smaller chunks, each directed to impact in a different section of the quadrangle. ''

''All five chunks impact within a span of ten minutes, throwing superheated gasses, water vapor, and debris high into the atmosphere. However, the impacts are smaller than the single massive impact that was directed to Syrtis Major Planum, as these impacts werent designed for brute force, but rather, for an entirely different reason entirely. The Arabia Quadrangle, long ago, was the site of an abnormally high water table, now frozen solid, and is a current source of the greenhouse gas methane emanating from under the ground. Each impact, spread out, bored into a different section of the ancient frozen water table, collectively warming up a large portion of it and causing heated geysers to erupt from the rapidly thawing ground, as well as providing escape vents for trapped methane, which starts to vent into the still-thin and cold atmosphere of the planet.''

''Water from the thousands of geysers formed by the melting of the water table soon begins to collect in craters, forming liquid lakes on Mars for the first time in hundreds of millions of years..... and soon, the lakes overflow, and the first flowing martian rivers in hundreds of millions of years begin to stretch along the barren, dusty surface of the Red Planet, occasionally merging with other new rivers and finding old riverbeds from Mars' warm past, forming great torrents that begin to rush towards the great basin of the northern hemisphere. Soon, the rivers reach the northern basin and begin to collect in a large icy pool, which grows and grows, becoming the nucleus of what will eventually be the largest ocean on Mars.''
