Science Fiction and High Fantasy being blended in a way that doesn't make sense
So, you've got an alien civilization older than Humanity, who've discovered faster-than-light travel ...
... And happen to be warriors, with a monarchy, who fight with swords/spears/axes instead of guns!
They've never heard of "television" or "fiction" before. Instead, for entertainment, they have gladiator tournaments! Huzzah!
Did I mention they've discovered faster-than-light travel? We're so primitive compared to them!
