Depends on who's on the other end of the p[hone]alantir. Who's got the other ones at this point? Anyone that could jump in to help out? Or at least be like "I have swarms of soldiers at my disposal. I think I'll order them to attack the King's Men and save the Faithful so that most of them can get off this blasted island before it sinks."?
Or there could be a villager uprising... or a really big earthquake that just so happens to, incredible as it may seem, drop all of the bad guys through a mysterious fault line that opens up beneath their feet, leaving the good guys just far enough away not to get crushed into some new style Numenorian Fertilizer as the fault line closes back up in the next tremor?
Or we could stick with "Run away, run away!" and trust in the speed of the kariborim and the tremors to keep any arrows from finding deadly purchase as we escape.
Or... I kind of like the Valar hearing Miriel's prayer. I just don't want to write the scene.
Now that you're back, LMP, that means I can foist her back off on you, right?
The most realistic sounding is to try and run away and trust in the earthquakes to screw up the soldier's aim. Surely a few arrows will land, and maybe there will be a nice depressing death just as the ships sail away and they'll have to toss the body into the churning sea...
Don't mind me. I'm just annoyed that high schoolers get the day off to celebrate a genocidal fraud and I'm stuck in classes.
It's got me in a cynical, pessimistic, and fantastically fun mood.
