“I am sorry. I believe this is as far as I go...”
—Moulder's death quote in The Sacred Stones
Moulder (モルダ Moruda, translated Mulder in the Japan version) is a playable character in Fire Emblem: The Sacred Stones. a mature priest of Frelia, he is gentle and reassuring. Well trusted by King Hayden, he is sent to aid Eirika alongside Gilliam and Vanessa. He is a very kind person and acts as a father-figure to most characters in the story. He seems either somewhat absent minded or too devoted to his work, such as in his A support with Gilliam, where he is revealed to have carried the crown at King Hayden's coronation, and dropped the crown when a young Gilliam yelled at him to get a hold of himself, or in his supports with Syrene in which he forgets his own birthday.
Moulder has some of the most offbeat stats. For example, as a Sage, he has a lot of HP and a really high Con, which is unusual. Despite that his Resistance and his Magic are rather low compared to the rest of the magic wielders in the game, he is useful at the Tower and the Ruins when promoted to a Bishop. Moulder, being a Priest, should have an A-Rank in staffs before you promote him, making him an effective healer (due to the staff rank and magic), and by the time he evolves, he should have a S-Rank in staves, so he can use Latona. Lute and Ewan can potentially be Sages, along with Saleh, who is a pre-promoted Sage, so adding another Sage would be pointless. As for Bishops, only Natasha and Artur can be promoted to it.
After the War of the Stones, Moulder continued to serve the royal family of Frelia. His wisdom served to guide King Innes as it had served King Hayden before him.
