Remember: everything Alduin says is made up.

Alduin reluctantly answered your call of his name into the skies. He took his time to arrive but arrive he did and landed before you with an angry snort like a bull. His horns a steely black and his eyes of deep red settled on you with a furrowed brow. "Speak, Dovah." He urged you, annoyed by your mere presence and use of his name. You who defeated him. You who stopped his plans.
