Things are happening. The guard in 0413 makes his morale check and doesn't flee. However, a rat skitters across the courtyard and engages him.
This guard is profoundly focused, however, and manages to ignore the rats in order to attack Sofia. He manages to roll a natural 20; his second d20 roll is a ten, so that he causes double damage. With his scimitar he causes 12 points, stunning Sofia and knocking her back into 0314.
Sofia has a wound and will now bleed 1 point per round on the enemy's turn, until she binds her wound or is able to receive magical healing of some kind.
The rest of the guards do not move forward and attack; they've found themselves beset upon by rats, about a dozen of them, and the shouting in the lane has become a din. There seems to be rats all around, but none of them are attacking the party.
Then, all of the sudden, Enrico's horse begins to freak out, rushing back and behind the tree in 0614/0714. A section of the courtyard falls out and collapses, leaving a black hole ~ it is too dark, with eyes not adjusted, to see what has caused it within a single combat round, so the hole is all you can see.
I want to emphasize that the rats are NOT coming from the hole; they have appeared to be coming from everywhere. No rats at all come from the hole.
The players can now make their move, excepting Sofia.
