Magnus’s RPG empire on the portal.

I cast a blessing on the assassins, then, flying upwards, I say, "Elves, I'm with you."

But suddenly, a gargoyle falls on you from behind and disrupts your flight path, sending you crashing towards the ground. You fall, but upon landing, you hear vibrations beneath you or feel the impact on the ground as an army passes nearby. An assassin runs up to you and says, "Go get help, we have a problem. The city is under attack." Before he can finish, a vampire's blade pierces him. What do you do?
