It takes a powerful and calculating woman to keep control of the White Tower and bring together the various Ajahs of the Aes Sedai. As Alanna warns Morraine, there are plots within the White Tower plots as the sisters watch Amyrlin’s headquarters. Specifically, looking at the current headquarters, Siuan Sanche. Independent, intellectual, and deeply understanding the need for teamwork, Aquarians have the skills to rule the Aes Sedai. Fortunately, these are traits that Siuan has in abundance.

Unfortunately, making the calculated decisions necessary to rule can make Siuan, like those in the water sign, impersonal and emotionless. The thing is, for the Amyrlin seat, it’s not a negative trait, but a necessary trait. She must plan, pass judgment, and lead a rebellious, yet incredibly powerful group of women. Siuan must do so while keeping her hidden mission silent, prompting her to banish her secret lover, Morraine, from the White Tower, never letting her shattered emotions slip through.

As for this hidden mission, it doesn’t become more Aquarius than that. Those of the last zodiac sign don’t spend too much time wasting in the past, or sweating the present – they are too focused on the future. Siuan has been steadfastly forward-looking for decades, ever since she and Morraine heard the Dragon’s rebirth prophecy. In fact, it consumed her, first as Aes Sedai and now as the seat of Amyrlin.
