Nothing is known about Rasmus' life prior to or as the outbreak began.
At some point following the outbreak, Rasmus joined a large group of survivors known as the Whisperers.
Rasmus is part of a small group of Whisperers that accompany Alpha to the Hilltop's gates. He then stops and listens as Alpha introduces herself and claims that she only wants her daughter, Lydia, back.
Rasmus is instructed by Alpha to help draw a herd away from the Hilltop gates. Later, when Lydia is returned back to Alpha, Rasmus leaves alongside the rest of the Whisperers.
Rasmus is in the field outside the Whisperer camp keeping a herd corralled. When a pair of Whisperers drag the bodies of Sean and Helen, Rasmus tells them to leave the bodies where they are and that the herd will come and feast on the remains.
