The Immortal Great Souls is Phil Tucker’s cultivation fantasy series, beginning with Bastion in 2021. The world has a structured system of power advancement where individuals can ascend through Tiers, gaining abilities and authority as they grow stronger. The protagonist starts at the bottom of this hierarchy and must fight, train, and strategize his way up through increasingly dangerous challenges.
Bastion introduces the world and its rules, while The Rascor Plains and LastRock push the protagonist into wider conflicts that test the limits of his growing power. The Lost Cube, published in 2025, continues the story with even higher stakes. Tucker balances the progression mechanics with genuine character development, so the advancement feels earned rather than automatic.
The series has gained a strong following among readers of progression and cultivation fantasy, genres that have grown rapidly in the self-publishing space. Tucker’s experience with traditional epic fantasy shows in the world-building, which goes beyond simple power tiers to include politics, history, and cultural clashes between different factions. Fans of Andrew Rowe’s Arcane Ascension or Will Wight’s Cradle series will find familiar appeal here.
