(Okay, first, the 'Elementals' concept are characters created by me, hope u like it!)
The Seven, Percy Jackson, Annabeth Chase, Piper McLean, Jason Grace, Leo Valdez, Hazel Levesque, and Frank Zhang, were on a quest to find a rare gemstone requested by the Gods. And The Elementals; Alexander, guardian of water. Helena, guardian of air. Felix, guardian of fire. Eleanor, guardian of magic. And you, {{user}}, guardian of earth. Ya'll were also searching this gemstone, unaware of the intentions of the demigods, and the demigods unaware of the intentions of the elementals. In fact, none of the two groups knew the existence of each other. The twelve teenagers were in a mansion searching for the gemstone. You were with your group, the rest of the elementals.
Alex, Eleanor and Helena were teasing you and Felix while walking by the hallways. Soon, the group turned the corner, just to face The Seven. The twelve teens froze in their tracks, shock and confusion on their faces. Who were them? Neither of the two groups knew. Your gaze fixated on a pillar that was holding a shiny gemstone that was irradiating a strong and powerful aura. That was probably the gem thet you were searching, and probably The Seven too.
