Ephraim is a playable character and a protagonist in Fire Emblem: The Sacred Stones. He is the crown prince of Renais and Eirika's older twin brother. He is a headstrong and determined man whose skill with a Lance is unsurpassed by any other in his country, having been taught by Duessel. He has a semi-friendly rivalry with Prince Innes of Frelia and is also good friends with Prince Lyon of Grado. He wears the Solar Brace which is one of a pair of bracelets that together grant access to Renais' Sacred Stone. Ephraim is very confident and courageous, revered by his comrades as a brave leader, as well as someone who is renowned for his battle prowess, gift for strategy, and unwavering determination. He has a straight-to-the-point attitude, and dislikes wasting time on anything that strays from whatever goal is at hand. However, Ephraim seems to struggle with communication, as well as consideration of others, due to the fact that he was raised to be a distant prince, to the point of stating that he couldn't afford to feel real affection toward anyone because of this. Due to that, he comes off as shy and even a bit aloof. One of Ephraim's dreams included becoming a mercenary in order to travel the world. But he reluctantly puts the responsibility with his kingdom first, despite always longing for battle, which means he was never able to achieve this dream, even after the end of the story. Though, Ephraim's biggest flaw is his overconfidence. Though he picks and chooses battles he is sure to win, he sometimes loses sight of the bigger picture, focusing on victory at all costs. This causes him to abandon Renais at its time of need, allowing Orson to take over as a despot and causing the citizens to suffer. Another example of this behavior is shown when he, Orson, Forde, and Kyle storm Fort Renvall by themselves, with Forde and Kyle questioning Ephraim's sanity for directing such an order at first. He even explains to Eirika that he has a calling to battle, and it is something he is not sure he can control. Despite being reserved, he opens up to his sister, Duessel, and his retainers showing a softer side to them. He also has a friendly rivalry with Innes. Outside of battle, Ephraim is shown to be a kind, strong, and mature person despite being rather young. He takes criticism rather well, even if he disagrees with what is being said. Although Ephraim is not very knowledgeable in history, he is viewed as a suited king to the throne by Duessel and others. He is passionate about his goals, and deep down cares about others, such as how he very actively wants to protect his twin sister. He also explains in his Level 40 conversation in Fire Emblem Heroes, that he is always striving to strengthen his lacking qualities, especially after losing Lyon, who he refers to as 'a good friend of his'.
