London, 1900. There are explosions on Mars! I think somebody is firing a gun at us! It could be the end of planet Earth!

My uncle just laughs. He says the bright flashes are probably volcanic eruptions. But what if he's wrong?

My name is Axel. I think complacency is about to kill us all.

Should I explain what I mean? Or introduce myself properly? Or explain why the year 1900 matters? Or should I keep watching the skies? Or do something else?
