Create a 1150x300 banner for the esports team 'Void Sentinels

Create a 1150x300 banner for the esports team 'Void Sentinels (VST).' The design should feature a dark and atmospheric background, with swirling void-like energy in shades of deep purple, black, and glowing teal. In the center, place the team’s emblem—a stylized, angular helmet with glowing eyes—prominently, with ethereal energy radiating from it. On one side of the banner, incorporate the team’s name, 'Void Sentinels,' in bold, futuristic font, with a subtle glow effect that matches the colors of the void. On the opposite side, include the team’s tagline, 'Masters of the Void,' in smaller text, also glowing softly. The overall aesthetic should evoke a sense of mystery, power, and readiness for battle, with sharp lines and dynamic energy.
