The modifications made are thoughtful and seamlessly integrated. Starting Epidemius in the Mine of the Bearded Skulls instead of his original vanilla location opens up numerous new tactical possibilities and interactions with different factions. The declaration of war with the Spine of Sotek dwarfs and Clan Pestilens from the get-go ensures a gripping, action-packed start to the game. The unique quest line featuring Skrolk, and the Cauldron of a Thousand Poxes as a reward, adds a much-needed personal stake to the conflicts, enhancing player engagement.

The ability for Nurgle factions to inhabit mountain regions is a subtle yet impactful change that expands strategic options for players. This mod is also commendably compatible with other popular mods, making it a versatile addition to any player's mod library.

While there are minor issues, such as Epidemius's victory objectives still being centered around factions near Kislev, the mod creator has promised an update. This commitment to improvement and the already enjoyable content make this mod a must-try for both new players and veterans of Total War: Warhammer 3.

For those looking to further customize their experience, this mod works well with other recommended mods like "True World - Light Start Position Changes" and "War for Eight Peaks - Dynamic Start Positions," enhancing the overall gameplay dynamic.

In summary, this mod is an exemplary work that revitalizes the gameplay of Total War: Warhammer 3. It's a testament to the creativity and dedication of its creator, promising a fresh and immersive experience for all players. Highly recommended for anyone looking to add depth and new challenges to their campaigns.
