The Deadlands Part Seven

Vanessa and I were followed out by Jacob, as he wanted to show us the town.
"Come on, i'll show you all the town." Jacob led them through a church, zoo without any animals and a store. But what caught our eye was a wooden wall being made.
It's was made out of logs with sharp tips and at each eight metres there was a watchtower.

"This is wall we're building." "Why?" I asked nervously,
scared of threat it was made to protect us from.
"Why do you think this town was abandoned? Danger. In the 50s a large pack with three leaders named Savage, Goliath and the main leader, a known man eater, Colossus.
Because no one hunted the three they swarmed the town, massacred everyone.
Some tried to gun them down but failed due to their numbers."
"Oh my god...how do you know this?" Vanessa asked, shocked.
"Because my grandfather was there."

Jacob continued to walk before he asked.
"You know my grandfather was the only survivor, and when he died here I vowed I'd never let it happen again. So I need your help."
We both were shocked, about this seemingly innocent town's bloody history.
"What do you need us to help you with Jacob?" Vanessa asked.
"You got chased by Snake Tongue's men, and they don't forget. They'll always search for you and now they know where you are. And it is said that Snake Tongue kill escaped prisoners himself."
"Go on..." I asked.
"And the walls won't be built by the time of the attack."
"Ok, so what information do you have?" Vanessa asked.
"The attack will be from the plains no th form here, and there'll so many of them."
"Ok..." I said. "Lets do it."
