Silas (Fallout 3)

Silas is a slaver stationed at the Lincoln Memorial. He is likely the lieutenant or underling of Leroy Walker. He is involved in the Head of State quest. If the player has already made an enemy of the slavers at Paradise Falls, Silas will still enter the original encounter speech, but as soon as he finishes, his men will open fire.
 * He wears a Merc Troublemaker Outfit and a Head Wrap, he wields a Chinese Assault Rifle
