Congratulations SV, you are Taylor's power! Or, more accurately, Taylor's power is to receive letters from you. One letter per day, that is. Of at most 100 words. But don't fret, you'll be able to buy upgrades to her power! Like more letters! And more words! Awesome, isn't it? No, you can't give her other abilities. Her power is letters, duh. But surely, with all your knowledge of the setting and future events, you can guide her safely to rescue her world! Right?
