Leaving Redlarch to try and help Westbridge (even though we know we'll
be too late), we come across half the town on the road, in harness,
dragging ... something.  They're being overseen by five azer, with
eleven mephits watching the perimeter and a remozhazz reserve force.
Oh, and the something turns out to be a leanarn hydra under a big wrap.
We don't have any way to kill the hydra (as it requires damage types
we don't have access to to prevent it regenerating), so we just force
it to pop more and more heads.  Turns out this is somewhat effective in
this edition (as opposed to suicidal), as it eventually falls over and
can't move.  17750 xp, +4k for rescuing the villagers.
