Lore accurate explanations only please

But seriously I'm calling this cliff racer down upon my enemies, it's the FIRST ability in my Animal Companions tree, and it's like... it's nuts. Like. Do you have any idea how metal cliff racers are? They are the most insanely depraved aggressive, untamable, jerks of animals ever. Did you ever try to walk from Ald'ruhn to Maar Gan? That's how I know!
But this ability, playing ESO, is making me like them. Look at that, they're helping me. They're coming down even into underground dungeons to attack my enemies. Bros. Absolute bros for that.
