So I was reading through Dragons of the Sixth World and I saw that the people on Shadowland were thinking the reason Kaltenstein fought Lofwyr and Nebelherr, was because these two were trying to prevent Kaltenstein from jumping in to the SOX to save Feuerschwinge. But the problem is the fight is said to take place in May, and the Sixth World Almanac says Feuerschwinge was shot down over the SOX in September.
So is this an error with the time of the fight in one of the books, or is the motivation for the fight not Feuerschwinge being shot down?
