Two sisters.

Regarding the return of heroes – unfortunately, I disabled the Portal to the City due to a bug that caused enemy troops to duplicate.

During the stage of capturing the first garrison, if you don't slow down, the Mage Guild won't be built, and the portal won't be available anyway. I meant the possibility of placing it behind the first outpost of the Fortress to improve troops (naturally, with decent protection). This would save time and wouldn't be a significant bonus, as by that time, the city already has the necessary improvements.
