"Generate an image of a medieval coat of arms featuring gold and black stripes, representing the House of Welf, a powerful and historic noble family originating from Germany, founded in the 9th century. The coat of arms should be set against a backdrop of a majestic castle, symbolizing their ancestral seats such as Schloss Herrenhausen, Schloss Marienburg, or Brunswick Palace. Incorporate subtle hints of their historical significance, including connections to the Holy Roman Empire, the British monarchy, and their rivalries with other European dynasties like the House of Hohenstaufen. The style should be a mix of realism and heraldic illustration, conveying the grandeur and legacy of the House of Welf."
