A medieval fantasy guild crest for a secret holy order of assassins. The emblem features a split symbol: a radiant golden sword partially concealed by a black shadowed dagger, crossing at the center. Behind them is a stylized half-sun, half-crescent moon, representing divine law and secrecy. The background is deep obsidian with subtle gold inlays. Surrounding the emblem is a thin circular sigil etched with ancient holy runes, softly glowing but restrained. The overall style is solemn, authoritative, and sacred rather than evil—no skulls, no blood. The lighting is low, with soft golden highlights emerging from shadow. High-detail, symmetrical heraldry, engraved metal texture, realistic fantasy art, muted color palette, 4k resolution. See more
