@Morzone: (Fixed! Did the math wrong.)

You can hear Brock weaving a tale as you search for a spellsong to practice. It gives you the motivation to practice as hard as you can for the journey ahead.

@Chakramaster: As you make your way inside, you can hear Brock speaking--apparently charge spells are involved in the story, as you can hear him say the incantation for a charge spell: "Obey the ancient pact of the ages and fulfill your duty..."

Of course he is not actually charging anyone--it is only for show.

(If he does charge anyone, Brock's charge marking is an elegant eight point star)
