Glacial Epoch

To start this quest, listen to Aurlyn's backstory, ask her if she remembers anything from her ancient past, then show an interest in helping her unravel this mystery. Travel to the Arcanaeum at the College of Winterhold for the next part of the quest, and talk to Aquillius Aeresius if you wish to purchase a ship for a long voyage afterwards, or board the Red Wave if you wish to privateer one, and speak to Aurlyn afterwards. Some scenes may fail to trigger; if that happens, then talk to Aurlyn, and choose the failsafe dialogue options to progress the story anyway. If Aurlyn isn't where you'd expect her to be, then just use her summon spell, Clarion Call. Thanks!
