Quote context

[...]

- Have no fear, my little one, soon your father will be home. And I must rest for the moment.

- Little one, I have so little magic left to leave thee. Use it wisely and well.

- On this small hoof, a magic mark I make. The Christmas star, cradled by a snowflake.

- And with this secret mark, the magic of the northern lights lives in thee.

- How, you ask? Think good thoughts and you will see.

- Will the magic last forever, you wonder? Nothing is forever, as I have often said. But this magic is strong...

- Your nose will glow, so long as you use it for good. If you are tempted, even once, to use it for an evil purpose, it will be extinguished forever.

- Do you understand? And will you never use it for evil?

- And now I leave you, little babe, to your mother's love.

- Use your secret magic well.
