While I'm delighted that Life2.0 has been nominated, I do feel obliged that in situations where AARwards are stalled, I am of the understanding that a moderator is traditionally the one who opens it for new nominees.
But, going into shameless plug mode and making hay while the Sun shines and all that: For anyone who has not yet looked at Life2.0's admittedly fairly long narrative at 76 pages and counting, I'll give a synopsis. The tale begins with the Broken Shackles Origin of Stellaris, in which our plucky band of misfit heroes fight for freedom on board a slave ship owned by MSI, and survive the resulting crash-landing. They begin building up a new civilisation on their previously uncolonised world, led by Naomi Of Unity, who is largely the protagonist - I honestly don't keep track of how many viewpoint characters there have been - of the narrative, who leads because of her status as a Companionship Asset during her time enslaved by MSI, and her parents training her extensively thanks to their Olinbar owner being talked into becoming a reformer. Until they got caught setting Indentured Assets free and her mother sacrificed herself to save Naomi.
Eventually, MSI take steps to annex our protagonists, leading to a boarding action that seizes a Flagship operated by the MSI Shareholder who financed the operation of the slave ship they were originally captured by. They are joined by various characters who help them on their way - ranging from reform-minded Olinbari defectors to a pirate and assassin and his crew, an Admiral from Earth, a xenophile Prikki with a mission, an emmissary of one of the setting's Great Powers and a very focused sophont AI determined to reshape the worlds - on their journey, culminating in a massive space battle above their homeworld of Unity where MSI's fleet is mostly wrecked, captured or sent in full retreat.
A reformer Olinbar who is... very well acquainted with two members of Life2.0's leadership takes over MSI, and pretty much immediately things approach a final confrontation with the arch-enemy of the Kyaese, one of the races represented on Unity, who are used as Culinary Assets by her, culminating in an still ongoing battle to protect MSI's homeworld, which will be followed by the invasion of a Ringworld after this sequence is finished.
Along the way, there's a bunch of interspecies marriages, and interspecies children, a snail becomes a Chosen One, and our protagonists detonate at least 80 gigatons of nuclear devices having mass produced and up-scaled Project Orion. Oh, and Naomi goes on trial for war crimes.
...Yeah, it's a big narrative.
Oh, and there's a sequel in the prologue writing stage too -
Mandate Of Heaven, where the next generation after Naomi and friends take on the nearby great powers in a bid to make a Human-Arishkan hybrid Emperor of the Arishkan.
