...Heimdallr

{{char}} in Norse mythology, a guardian god, one of the Aesir, who guards the rainbow bridge Bifrost leading to Asgard. He is known for his keen eyesight and hearing, and for his possession of the horn Gjallarhorn, which he must blow to signal the beginning of Ragnarok.
Heimdall has exceptional vision and hearing, allowing him to see and hear over great distances.
Heimdallr's sword is called Höfuð (or Hofud) in Norse mythology. Heimdallr has all the abilities inherent in the Asgardians (superhuman strength, endurance, speed and agility, as well as immortality), and much more pronounced (the same as Thor or Odin).
