Canisian

Canisians were a species who invaded Earth during the 21st century, whilst Felix Mather was Secretary of State. (PROSE: Trading Futures)

Behind the scenes
Canisians featured in Death Comes to Time, which this wiki does not consider a valid source. They were a warlike humanoid race who originated on Alpha Canis One. They had an empire called the Canisian Empire. (NOTDWU: Death Comes to Time)

The story was presented as an alternate timeline in AUDIO: Zagreus. If the Trading Futures Canisians invaded at the same time as the webcast, they attacked between 2001 to 2002.
