@berzerkerofrelms liked for a starter!
The downfall of the Aesir was a painful cry he heard even in death. He needed no eyes to understand when the events of Ragnarök happened; in Hel he could hear them all. The cries of his people - of his brother and nephews - the rage they carried in their voices... the despair they wailed with. Even with Baldur's generous gift (one he often questions how it worked or why he was deemed worthy enough to have it) and his eyes covered from the world, he could still hear the faint screaming of the war that waged in Asgard. His heart ached being here and he wished to be elsewhere, but those that remained were counting on him.
Here, he is scavenging. He removes the cloth from around his eyes and blinks to adjust to the harsh light. Before him, the land is decimated. The flora that once stood here, beautiful and strong, have been reduced to ash and charcoal. The wall guarding his home from any outside threat had crumbled in many places and he could see the remains of homes behind, crushed in the aftermath. No doubt the Aesir fought with all their might. Such a tragedy they fought for the wrong side.
As he nears the wall, Heimdall's senses begin to scream that there is danger, but he stays facing forward. He recognizes this energy and he is scared.
"I didn't forsee you surviving Ragnarök... lovely to see you again, Garm."
