My attempt at breaking down the OP's narrative
anolysis: Shor son of ShorAnd the awful fighting ended again.
"Kyne's shout brought our tribe back to the mountaintop of Hrothgar, and even our recent dead rode in on the wind of her breathing, for there had been no time to fashion a proper retreat. Their corpses fell among us as we landed and we looked on them in confusion, shaken as we were by this latest battle in the war of twilight. The chieftains of the other tribes still held their grudge against our own, Shor son of Shor; more, they had united finally to destroy us and used skin-magic to trick us into disarray.
Kyne uses Th'um (the voice) to teleport members of a warring faction back to the top of High Hrothgar. I believe this to be the tribe of humanity. Since mortals were created by the Aedra, they, have aspects of each of those creators among their group. That is why you see Kyne, Dibella and Mara in this tribe. This group is led by Shor and have just fought a loosing battle against the Aedra. This fight is a recurring fight and it happens at the twilight of each Kalpa. If the Aedra win, Alduin shows up and the world is consumed
"Shor was disgusted with the defeat, and disgusted more when reminded by Jhunal that our withdrawal had been wise, for we were outnumbered eight to one. Shor took on the form of his Totem then, which he used to better shape his displeasure, rather than to shout it aloud and risk more storm-death. His shield thanes, the brothers Stuhn and Tsun, bowed their heads, collecting the spears and swords and wine-knives Shor threw about the broken pillars of the easternmost sky-temple. The rest of us looked away and to our own, not even to acknowledge the thunderclap that signaled our Queen's arrival, who stepped in from the tunnel of her own breath last.
Shor can barely contain his rage at this retreat even though it was an unbalanced eight to one fight. If he shouts there will be deaths so he throws things around instead. As the rest of the group cowers, Kyne is the last to be teleported in from the battle
"Kyne had taken the head of Magnar, the jarl that betrayed the weakness of our spear-lines and fled the field. Shor shook his scaled mane. "That isn't Magnar," he said, "Magnar, I fear, fell at sunrise and became replaced by mirrors. The other chieftains are using our forms to lead us astray."
Shor quickly recognises that the hostile Aedra have used impersonation to exploit weaknesses within his ranks
"And then Shor walked away from his War-Wife to enter the cave that led to the Underworld. He needed to take counsel with his father yet again. "Our chieftain loses heart," Dibella said, Bed-Wife of Shor, hefting another body onto the corpse pile some of us were making, "And so goes to the speak to one that has none anymore. Mirrors, indeed, and in that I see no logic."
The monomyth clearly states that:
The magical beings of Mythic Aurbis live for a long time and have complex narrative lives, creating the patterns of myth. These are spirits made from bits of the immortal polarity. The first of these was Akatosh the Time Dragon, whose formation made it easier for other spirits to structure themselves. Gods and demons form and reform and procreate.
Aedra can form and reform and procreate. So Shor may be a true offspring, form or reformation of Lorkhan.
