Funny and amusing situations...

After Purple's turn, I couldn't understand for a while where his hero had gone. Looking at the world map helped me figure it out: I don't know if it was a coincidence, but it seemed like he had hidden behind the Veil of Darkness! Or maybe he just stopped for a smoke? :)
Update: it turned out he just didn't have enough movement points: the next day, he activated the Veil of Darkness and rode on (but that won't save him from retribution!).
