( Ok. How about he attacks the village before he realizes Nidhogg is not there. He's blinded by rage at the moment, so that will buy your guy time to get to the port. )
Ducking into his own homestead near the village, he places the baby monster into the back of his old, half rusted truck, not bothering to tell his wife where he was going, but shouting to her to get the children to the root cellar.
Calling back to him, surprised, from their shanty, she questioned him with a toddler on her hips. " Just do it, woman, don't question me. I have to leave now, I'll be gone a few days. You need to shelter in the root cellar now!"
With that, he hopped in the rust bucket, gunning it through town down the dirt roads that lead to the port city on the coast. He knew the further he got, the less likely he would be caught. He only hoped that his wife and children made it to the shelter before those winged monsters followed the scent trail to the village.
