Unicorn Empire

I dealt with the mage, now I have a question about the quest to escort Arantor. I brought him to the end of the map, but he's just standing there and not doing anything. What should I do?

I supported the Necropolis faction) and used it to defeat the Inquisition in the final battle)
The Necropolis faction really saved the day) I thought I had lost with my human troops, but then the Necropolis faction arrived! I was surprised))) The author created a surprise))))
