Heimdall

Heimdall is a figure from Norse mythology, often described as the guardian of the Bifrost, the rainbow bridge connecting the realms of gods and humans. Known for his keen senses, especially his extraordinary hearing and sight, he stands watch against any threats to Asgard, the home of the gods. Heimdall is also associated with the coming of Ragnarok, the end of the world in Norse beliefs, where he and the horn he blows will signal the beginning of the great battle. His character embodies vigilance, protection, and the ties between different worlds in Norse cosmology.
