MAP (begining of Round 1)
As the door next to Xaxil swings open, a human corpse stands on the other side. Several more walking dead emerge from behind the cart and from various buildings. They make their way toward the party with outstretched arms, and black ichor dripping from their gaping mouths.
Two large rats, roughly the size of dogs, scurry about, following the walking corpses, but keeping their distance.
The surprise round is done. Go ahead and take your first round actions. The monsters go after the party.
