Something does not fit in the storyline

[.:Pandemonium:.]

There is an easy Sci-fi explanation to the extended trailer :D :

In distant future when Sirius is fully colonized, and no planet, asteroid or piece of rock in reach is free for human colonists to settle will be there only possibility to colonize nomad worlds and their space. With superior human technology and warmachine before unseen there will be another human-nomad war much bigger than the first war, but this time the nomads are going to extinct. With their last breath the nomads are sending back in time the sun destroyer to kill their enemies-humans at birth. But they messed something up and they arrive few minutes after the sleepers ships were launched. Dont aware of that they destroy the sun and are celebrating a party in their cloaked ship. :crazy::lol:
