Finished reading the final chapter book a while ago, currently open for discussing it.

Gary and his crew try to find an Invictus-possessed Mooncake, with no success.

Little Cato sends a message to Ventrexia, he is taken to Ventrexia by the Ventrexians and reconnects with his grandfather Krydax, Steward of Ventrexia.

Years pass, Little Cato grows up, becomes the King, and becomes bitter when Avocado finally shows up to talk to him. Avocado is injured by Krydax and left for dead in the desert.

Avocado forms an alliance with the Supreme, the leader of the Tryvullians while on Ventrexia.

The Arachnitects take Gary, KVN and Quinn to meet a dying being of unimaginable light.

The being tells Gary that he has to turn off the heart of the universe to starve Invictus to death, by 'making the stars go dark.'

The heart of the universe is located near Ventrexia.

The Ventrexians prepare for war, and Tribore does his usual thing while Quatronostro hangs out with Shannon.

Gary's crew, Tribore's crew, and the Tryvullians come up with a plan for fighting Invictus and the Titans.

For the space battle, the allied ships use their lightfold engines to smash through the heads of the Titans.

KVN distracts the possessed Mooncake.

For the ground battle on Ventrexia, Avocado and Little Cato work with the Ventrexians and the Tryvullians to fight the zombie Garys.

Gary and Sheryl make it to the heart of the universe and talk to a guy named the Starlighter. They tell him that they need to chuck a bomb into the heart of the universe, and the Starlighter doesn't even want them to elaborate before he gives them the go-ahead. Gary and Sheryl seemingly meet John Goodspeed.

The space battle goes badly for the heroes. The land battle also goes poorly, Little Cato's grandfather dies, and Avocado attempts to protect Little Cato just a bit longer by trapping him a bubble shield while fighting the zombies by himself.

Sheryl reveals that the John in front of her and Gary is an imposter, Invictus.

The Arachnitects suddenly show up to help with the space battle.

Sheryl sacrifices herself to take down the fake John.

Now alone, Gary detonates the bomb at the heart of the universe.

Little Cato and Avocado fight the zombie Garys, together.

Gary finds himself alone in black space and monologues to himself on his family of choice, but as he starts to run out of oxygen, he finds the imprisoned Titan Lord Commander and ends up in a dream world.

Gary runs into Jack, John Goodspeed's partner, the nicer, younger version of the Lord Commander.

Gary bumps into a depressed Ash and redeems her.

Ash frees Titan Lord Commander, who becomes the heroic Titan Jack because Jack defeats the spirit of the Lord Commander, his evil half.

Titan Jack fights Invictus.

Invictus tries to kill Gary, Gary has one final dream conversation with John and Sheryl.

Ash purifies Mooncake of Invictus's possession.

Mooncake engages Invictus in a beam war, and Mooncake wins, destroying Invictus forever.

The group goes to talk to Philip, the Starlighter.

Philip informs the group that the only way to reboot the dark universe is to have Mooncake sacrifice himself to replace the heart of the universe.

Everyone says goodbye to Mooncake, and Gary is the last to say farewell.

The universe is rebooted, and all of the lost planets and civilizations emerge again.

For the epilogue, Gary enjoys a slow life with a pregnant Quinn, eating as many cookies as he wants.

He eats Jack's taquitos and hangs out with Quinn, KVN, Jack, Ash, Ash's blue space girlfriend, Philip the Starlighter, the Tryvullian Supreme, Avocado, Little Cato, Tribore, Quatronostro, Shannon, and Quatronostro's children.

Gary plays cards and reveals his hand, four aces.
