According to sources that I've heard, any reference to the sufferer's revolt was forbidden, even in private journals

Source: "[The Summoner] would exhi8it a remarka8le pup8tion, the sort only recorded in myth, growing, or perhaps simply revealing, a striking pair of wings. His army thus inspired would spearhead a major re8ellion. Surely one at least on the scale of the sectarian revolt crushed 8y the High8loods, who thereafter for8ade its mention, or any invoc8tion of the heretical sym69ls at all, even in private journals. Which is why I will stick to the fa8le of the summoner, and not risk another execution with even o8lique reference to the compelling tale of the sufferer."

If Havres is to have read the history from any Alternian books, he likely would not know about it from there. His knowledge of the Sufferer, if it is to exist, could perhaps be presented in a different way; maybe by contact with one of the followers of him that existed around the times Havres was around
