So much history passed from human knowledge during the Cataclysm that we find it hard to realize just how much was lost. This is particularly true of the last few centuries before the dire event. Knowing what came to pass, we tend to ignore the whole era and fail to assemble even the few bits of knowledge we have into the best picture we can build.
A classic case: Sir Pirvan, called the Wayward, Knight of the Rose, and his associates, some of whom have come down only as names.
Various chroniclers have placed him at various times during the millennium before the Cataclysm. The best evidence, however, suggests that he was some thirty years old when he made his first appearance on the rolls of the Knights of Solamnia, in 181 PC. This would place his date of birth somewhere before 210 PC.
Such as Pirvan are undeservedly forgotten. When they were born, the kingpriests were not yet a menace. When they died, the kingpriests had become tyrants. During their lives, they carried the weight of the fight against that tyranny. They lost, but had they not fought at all, one wonders if the gods would have spared any part of their creation when their wrath descended upon Krynn.
