Jacques Lime

Jacques Lime was a student and artifact hunter from North America in the early 21st century. 

History
In his youth, Jacques, Quinn, and their friends, discovered clues that led them to travel near and far in an effort to unearth five mytical crystals. (The 5 Crystals)

Jacques would continue a pattern of adventure-seeking and bringing his friends along in several clue-dropped searches, including seeking five gems and five diamonds. (Take Out Ville: "The 5 Diamonds", "The 5 Gems")

Learning about a recently earthquake-uncovered entrance to an ancient temple, Jacques traveled to Mexico through his class in-field archaeological-dig program to investigate. After separating himself from his class, he snuck into the temple and was confronted by two Mexican drug cartel thugs. Defeating them, he found Itzcoatl's last codex and escaped after triggering a temple self-destruct mechanism. Returning home to North America, Jacques donated his find to the museum director but also incurred disapproval of his methods from his archaeology teacher at King's Crystal High School. 

Being in possession of photos of Itzcoatl's last codex, Jacques spent days trying to decipher it. Later, he chance-encountered his friend Quinn at the school library, where Quinn was able to figure out that the codex was describing something being passed down generation after generation, ending at Teotihuacan. Realizing the implications of this, Jacques engaged in an impromptu trip to Mexico, unexpectedly joined by Quinn. At the airport, Jacques carelessly used his school's trip credit card to purchase the tickets. At Teotihuacan, both Jacques and Quinn were ambushed by a crime syndicate group, who revealed they stole Itzcoatl's codex from the museum. Fighting them down, quickly, Jacques led Quinn toward a temple entrance in haste.
