She trains. She learns.
Talos gave her something, when he Named her. Some innate understanding, of each of the words she had read from the book that afternoon. She goes over them in her head that evening, curled up in her bed with her bedcurtains closed, portable desk, parchment, and charcoal in hand.
Ahkrin - Courage
Bel - Summon
Geh - Yes
Sos - Blood
Meyz - Become
Thu'um - Voice
Strun - Storm
Du'ul - Crown
Tuz - Blade
Gron - Bind
Vokun - Shadow
And, of course,
Dovah - Dragon
Or
Dov - Dragon
Ah - Hunter
And
Kiin - Born

Summoning storms and becoming shadow, two other possibilities she can see, seem perhaps too dangerous, however.
