When travelling through time and space it helps to have somebody by your side. Somebody who, preferably, has some idea of what's going on. Unfortunately for Damien beggars can't be choosers.
Damien is stuck with one person who knows his secrets and can help him set right what once went wrong. The unreliable immortal he calls his companion doesn't really bother to keep up to date with current events. So, he does his best to piece together what Klaus can provide.
With help from the locals and the friends they make along the way they do their best to survive to see another day.
