The Last Watchdog

He was a celebrated war hero content to run a junkyard on the galaxy's lawless edge, his genius for strategy buried beneath a desire for peace. But when a found family of outcasts seeks refuge under his protection, he must awaken his forbidden connection to a god-like war AI to defend them from relentless forces. Rising from humble scavenger to master of an ancient, planet-sized fortress, he forges a haven for the forgotten, challenging a decaying empire and the ghosts of a forgotten age. Yet his greatest battle lies within, as he unravels the truth of his own identity: a living key to an ultimate weapon. In a cosmos where wars are won by clashing philosophies, he must choose between a pre-written destiny and the simple home he was never supposed to have.
