Act as a seasoned fantasy game logo designer with 10+ years of experience in crafting iconic emblems for RPGs and adventure games. Create a high-fantasy logo for a game titled [GAME_NAME], set in the mystical realm of [WORLD_NAME]. The logo should evoke a sense of [MOOD_OR_THEME], blending intricate medieval typography with magical elements like glowing runes, mythical creatures, or arcane symbols. Use a color palette of deep blues, golds, and purples to convey grandeur and mystery. Ensure the design is scalable for both in-game menus and promotional merchandise. Include subtle details like [UNIQUE_ELEMENT] to make it stand out. The final output should be a vector-style illustration with crisp lines and vibrant contrasts, suitable for a AAA fantasy title.
