"A powerful, princely figure sits in a swift chariot,… He or she may hold a sword or wand, or other masculine symbol.
Another view is that the mood of the card may be characterized as that of conquest. It represents a battle that can be won if the Querent has the willpower for it. The battle is usually an external one, with a clear goal and plan of action.
Control is required over opposing emotions, wants, needs, people, or circumstances; to bring them together and give them a single direction, your direction. Confidence is also needed and, most especially, motivation. The card can, in fact, indicate new motivation or inspiration, which gets a stagnant situation moving again. It is armored, but also cut off - a charioteer fights alone. On the other hand, however, the Chariot may signify a ruthless, diehard desire to win at any cost. The danger is getting on the wrong path - being overwhelmed and dying before our due time.”
Eridan riding the chariot reminds us that of all the guys flaws, his largest and most prevalent one is his ambition. Like Vriska, Eridan is trained in the art of theatricality, and often over dramatizes details of his on life to suit his whims and wants. He is also strong, very strong. Yet his strength is, like Equius’, his hindrance: he uses brute force to destroy his consorts, never stopping to consider other alternatives. The Chariot also represents an unchanging path; once you start down it, there is a chance you’ll never be able to stop. But getting back to Eridan’s ambition… the boy has goals, and he will do ANYTHING in his power to achieve those goals. He duels Sollux, a high level psiionic, just for the chance to woo him and Feferi. He takes his role as Prince of Hop very seriously, and even attempts to use hope in a way to save the one he loves in what he perceives as an unwinnable situation. Eridan’s chariot just will not slow down, not for anything or anyone, and he ultimately drives of a cliff in the thing.
