Serverian

When a freak accident claims her life, Riley finds herself inexplicably aboard a strange spaceship, joined by seven other souls who perished at the same moment.  Initially terrified, they gradually forge a bond in this unexpected afterlife, transforming the sterile vessel into a haven of camaraderie.

Their newfound peace is shattered by the arrival of a cryptic message from a powerful entity known as AXIS.  AXIS tasks them with a critical mission: journey to different worlds teetering on the brink of collapse, identify the source of their turmoil, and restore balance.  The eight become unlikely saviors, traversing the cosmos and leaving legends in their wake.

They are first sent to Sveethlad, a diseased world on the bring of breaking apart. They are tasked to save it. They will,  but doing so would fundamentally test the bonds they've built the time they were in the spaceship and after a while they are sent to several more worlds to save. 

Their latest mission however, the Axis system would suffer a glitch, Riley would find herself transported to another world, seemingly on the brink of destruction, the only difference is that she had been sent there ten thousand years too late, and all her friends have become gods. It should be the best thing ever but many things are not right in this new world, most of the gods are asleep, one of them is missing and another one is dead. Riley would have to find out what happened to her friends in the time she was gone, why they became they way they are and if, perhaps it was all inevitable from the start.

The grim hush of the upper streets felt almost benevolent compared to the suffocating depths he'd just crawled from. Still, the remnants of that place clung to him—foul spores in the folds of his clothes, a toxic stench that no amount of brisk wind could chase off. He'd gone down there seeking a fast route to more power, had nearly died in the process, but now the Axis terminal in the periphery of his vision listed a triumphant new entry: "Dungeon Cleared: Rotten Church Depths." A flush of XP had coursed through his body the instant he'd stumbled back into daylight.
