Fern learns the importance of sleep!

Fern

Just one more spell to master before dawn...

Fern

I can't let Master Frieren down!

Frieren

Fern, it's the third night you've stayed up. Even mages need rest.

Fern

But Master, there's so much to learn! Sleep feels like a waste of time.

Fern

I want to be as knowledgeable as you someday!

Frieren

Come here, Fern. Let me teach you a crucial lesson about magic.

Fern

A new spell, Master?

Frieren

The most powerful magic of all: a good night's sleep.

Frieren

It took me centuries to learn its importance.

Fern

But Master, I don't think I can...

Frieren

And that, my dear apprentice, is the true magic of rest.
