Design an emblem for a team named 'Void Sentinels.' The icon should feature a dark and mysterious color scheme, with deep purples, blacks, and hints of glowing blue or teal to represent the power of the void. In the center, place a stylized, angular helmet or mask with glowing eyes, symbolizing the sentinels who guard the void. Surround the helmet with ethereal, swirling energy patterns or wisps of smoke, giving a sense of movement and otherworldly power. The overall shape of the emblem could be circular or shield-like, with sharp, clean lines to convey strength and vigilance
