Design a dynamic YouTube channel cover for a history-based channel named Waj TV

Design a dynamic YouTube channel cover for a history-based channel named Waj TV, which focuses on historical facts and great figures who have had a lasting impact on the world. The cover should be visually captivating, featuring a blend of prominent historical figures such as Mahatma Gandhi, Napoleon Bonaparte, Albert Einstein, and Buddha, all positioned in a way that symbolizes their contribution to the modern world. Incorporate elements like an ancient scroll, world maps, or historical artifacts that subtly highlight different eras and cultures. The color scheme should be a mix of rich earth tones (like browns and golds) with accents of royal blue or deep red to convey a sense of importance and grandeur. The title Waj TV should be bold and prominent in the center, with a tagline below it, such as 'Unveiling History’s Greatest Legends.' The overall feel should be educational yet inspiring, drawing viewers in with a promise of profound historical insights."
