Thousands of years ago, a large population movement began as the Viords, a Germanic group, pressed from behind, began to invade the Pictish islands.  It soon turned into a medium-scale war, though it probably seemed like a full-scale war to those involved.
The leader of the Viords told one of his generals that he wanted to assault and take a particular tor because it would be strategically important.  The general blanched.  "Excellence, it will cost me dozens of men to take that hill, and I doubt that we could hold it."
"Silence!" roared the Viord leader.  "I don't care how many men it takes.  Everyone knows that one Pict tor is worth a thousand Viords."
