"They do," Magnus says. "It's a religious thing. A month of daily fasting and prayer. No food from dawn till dusk. We were kind of worried, when Sam was fasting during our voyage? Partially because technically you're allowed to break your fast if you're traveling or in danger, both of which we were. Alex and Amir -- Sam's betrothed -- were both particularly concerned that she'd be physically weaker from it. It worked out for her, though; she said her focus on her faith protected her from freezing to death in Niflheim, the same way that Alex kissing me saved me. Um, maybe both of us, actually, because after she kissed me I could call up some warmth again." He's blushing, remembering that kiss. "Fasting made Samirah stronger against Loki, too. But the actual fasting on the actual boat was clearly really hard on her. So I guess... maybe?" He nudges Galahad. "Did you fast a bunch? Back home?"
