Slight error in the chronology?

Harpies in Felarya tend to despise sphinxes, which they see as little more than a bunch of full-of-themselves and self-righteous morons, and have fought several wars with them.

Ummm what wars were those? I don't even remember a foot note in history unless you count the lore surrounding Torin. Which I don't believe was included in the Chronology, or am I mistaken?

Son, 'tis what happens when a race is rarely used, you forget details that were intended to be integral to world-building. That or they were minor wars that weren't worth discussion much, either works.
