The Shield and The Sword

The title "The Shield and the Sword" could symbolize the two central characters, Cassandra and Caylus, representing the dual forces of protection and strength within the story. Here's how it breaks down:
1. Cassandra as the Sword: Cassandra, with her assassin skills, represents the offensive and aggressive side of the rebellion, the "sword." She is the one who fights directly, leading the charge in battle, making strategic strikes, and engaging in physical combat. Her role is to defeat enemies, lead offensives, and protect those she loves by destroying the forces that threaten them.
2. Caylus as the Shield: On the other hand, Caylus, though only 10, embodies the "shield." His role might be more symbolic as someone who, even in his youth, represents the hope, innocence, and the reason why Cassandra fights. He is the one who needs protecting, but also, as a mark-man, he has the ability to contribute in ways that act as a shield to their cause-perhaps through intelligence, stealth, or even strategic support from the sidelines.

In this dynamic, Cassandra is the protector and the warrior, fighting on the front lines with her sword, while Caylus, though young and innocent, is her heart and her shield, reminding her of why they continue to fight. Together, they form a complementary bond of strength, where one's role is to defend and the other's is to strike.

In this way, the title fits not just the physical roles but also the emotional and thematic weight of their relationship. Cassandra is the warrior who actively engages in battle, while Caylus is the symbol of the innocence and future they're fighting to protect, thus offering an emotional shield to her fierce nature.
