“Lady Maria, please forgive me. I could not refuse my Lord Ahab's orders, and thus I helped the destruction of the Salia Royal House... This sin is without redemption.”
—Zachariah, in a conversation with Katri
During Ahab's coup against the royal family of Salia, Zachariah received orders from him to murder Princess Maria in the forest. Instead of fulfilling his orders, he entrusted her to the care of Law, whom he met there. He later ensured that King Dagnell and Queen Maria were imprisoned instead of killed.
During the game's events, Zachariah is ordered by Ahab to capture the city of Blood from Lionheart. However, he is defeated by Holmes's army and spared by Katri, whom he recognizes as Maria upon seeing her holy markings. Afterwards, he assist Holmes's army in defeating Ahab and soon reveals the whereabouts of Glaus and Maria.
Zachariah's stats are typical General stats - high Strength, Defense and HP, with average Skill and Speed. He is a solid wall when first obtained, as well as being a good filler character in the endgame. However, he is hit hard by his low growths, lack of skills, Big Shield aside, and low movement with no way to increase it without using items. Ultimately he will become worse than both Norton (due to movement and better offence) and Billford (due to his skills).
“Fine, I shall be your opponent!”
