re: Crackpot ASOIAF Theories SPOILERS

IIRC, it had something to do with fighting over control of The Reach.

It was a brief comment in The Sworn Sword when the Ser Eustace is reminiscing over a broken shield he pulled out of a box (pg. 16 on my Adobe reader). The passage reads:


"The Little Lion's shield." The old man rubbed at the rim, and some flakes of rust came off. "Ser Wilbert Osgrey bore this at the battle where he died. I am sure you know the tale"

"No m'Lord," said Bennis. "we don't as it happens. The Little Lion did you say? Waht, was he a dwarf or some such?"

"Certainly not." The old knight's mustache quivered. "Ser Wilbert was a tall and powerful man, and a great knight. The name was given him in childhood, as the youngest of five brothers. In his day there were still seven kings in the Seven Kingdoms, and Highgarden and the Rock were oft at war. The green kings ruled us then, the Gardeners. They were of the blood of old Garth Greenhand, and a green hand upon a white field was their kingly banner....."

A quick comment, but it struck me to know that the two lands (even though Lannisters are not Casterlys) have been enemies.
