Interlude 1
The Curse of Holten begins at The Refuge and returns to Ogham to recruit the Ezomytes.
Campaign progression

After Act 4, the campaign branches into three Interludes: The Curse of Holten, The Stolen Barya, and Doryani's Contingency. You can complete them in any order. Their area levels scale as bosses are defeated across the other branches, and completing all three leads into endgame progression.
Each branch has its own town, route, bosses, quests, and permanent rewards.
The Curse of Holten begins at The Refuge and returns to Ogham to recruit the Ezomytes.
The Stolen Barya begins at The Khari Bazaar and follows Sekhema Asala's interrupted Ritual of Water.
Doryani's Contingency begins at The Glade and searches the Azmeri mountains for the Cuachic Vault.
The branches are independent, but progress in one changes the levels in the others.
Interlude area levels permanently rise as bosses are defeated across the other branches, reaching eight additional levels by the end.
The penalty is based on zone level: 40% at levels 54 to 59, 50% at levels 60 to 64, and 60% at level 65 or higher.
After all three branches are complete, The Hooded One in Kingsmarch grants the Interlude Book of Specialisation for two Weapon Set Passive Skill Points.
