Mythology

"The Gjallarhorn - 'horn of alarm' - was carried by Heimdall, the watchman who sat at the edge of Asgard and reported the first signs of danger nearing the gods' realm. It was said that when Ragnarok approached, Heimdall would sound a blast from Gjallarhorn that could be heard throughout the nine worlds."

Trivia

In the pre-Retold name, the first word of this technology should be Eldhrimnir, from the Old Norse words eld ('fire') and hrimnir ('sooty').
