Has anything more specific than "1602" been stated anywhere for the conquest of Sartar (I need to figure out what rough season the Hendriki left their tulas to die at the Battle of Caroman Pass, but an idea of the general dates would also be helpful).
Presumably the Empire began the attack in summer, when their (Dara Happan at least) magics are more potent, rather than the alternate campaigning period, during Storm/Darkness.
