The confirmed relationship loop
Building a deeper relationship with an ally can unlock additional conversations and personal quests. The published system also allows some relationships to develop into romances.
Stronghold connection
Allies are tied to the home-building loop: investing in their facilities expands related services, crafting options, shops, or plots. Treat relationship progress as part of a world and its people, not as a character-stat shortcut.
What is not named yet
A complete romance roster, gift requirements, and exact thresholds are not confirmed here. Wait for the current game to identify romance options instead of labeling every named character as available.
