"Flight to Salvation" - "The Veil is Torn" [Campaign 4, Mission 2]

I gave the Tear of Avarice to Duncan. Frida easily dealt with the demon. In principle, we can leave her with Zehir, but there are already plenty of reinforcements in the form of monsters in front of the castle, and there is more than enough gold, even if you don't take them right away. So, the Tear doesn't play a significant role.
