Final prompt:
Use case: logo-brand. Create a single finished application icon for the new brand UMBRA, a premium modern Windows companion app for an old-school fantasy MMORPG. A bold, original U-shaped eclipse emblem, one restrained violet inner glow and pale platinum/satin gold edge, with a dark indigo core. Simplified strong silhouette, calm, precise, readable when reduced to 16x16 and 32x32. No letters or wordmark, no R, no existing brand reference, no game logo, no busy filigree, no background scene. Centered icon with generous transparent padding, square canvas, genuinely transparent background outside the emblem. The overall mark should feel exclusive and quietly mysterious, suitable for a graphite/plum application UI. Deliver just the one crisp emblem, no mockup, no variants, no watermark.
