Alina decided not to leave.
Leaving would only make her a traveler.
Staying would allow her to see how far she could go down the path of an astrologer.
Even if the road proved impassable, she could always return to being a traveler. At least, she'd have tried.
Roland suggested Alina start with his enemy.
"First is the former vice-captain of the Knight Order, Warden, but you should hurry."
Alina understood implicitly. She disguised herself and, guided by Roland, entered the Knight Order.
Through the window, she closely observed Warden, who was feasting away. After a moment, she came to a conclusion.
Warden's fate was dark; his life force flickered like a dying candle in the wind. By tomorrow morning at the latest, his life would reach its end.
The results of observing fate couldn't be directly told to others; otherwise, there'd be backlash.
This is the real reason astrologers are so cryptic in their words.
It's not that they particularly enjoy being enigmatic.
