[Atlas]

The gathered crowd was silent. Moments before they had been a mob, villagers carrying axes, hammers, any and every wicked instrument they could grasp. Now they circled around the boy they had slaughtered. His body was barely recognizable as human, his hair torn from his head by the hands of many and his face bloody, bruised, swollen from their vengeance. His once-fine clothes lay in tatters around him, his body ripped open from the work of the village. But the crowd no longer looked upon him with hate, but with dread, terrified at what they had done. The Storm Lord's son was dead, and retribution would surely follow.

Good morning to you, Atlas,

Moments before they had been a mob, villagers carrying axes, hammers, any and every wicked instrument they could grasp.

I'd suggest using a colon after 'mob' because the rest of the sentence is a description of them. 'Villagers' is in apposition to 'mob' but is imbedded in a phrase. I would also advise you to delete 'any'.
SUGGESTION: Moments before they had been a mob: villagers carrying axes, hammers, and every wicked instrument they could grasp.

'circled around' is redundant. Of course they are going to circle around someone - unless they square around someone.
SUGGESTION: Now they circled the boy they had slaughtered.

This is a list of things that have happened to the poor boy's face. You need to include an 'and'.
... and his face bloody, bruised and swollen from their vengeance.

This doesn't make sense. The villagers killed the boy, not the village. At no point have you explained if gruelling work was to blame for this boy's death.

1 ) *cringe* Try not to start a sentence with a conjunction (and, or, but, either, neither, nor). It's like farting on your food before eating it.
2 ) If you are bound and determined to start a sentence with any of the aforementioned conjunctions, try not to use the same conjunction later on in the sentence.
3 ) You can delete the first comma without changing the meaning of your sentence.
SUGGESTION: The crowd no longer looked upon him with hate but with dread, terrified at what they had done.

Well done! You have a fantastic opening here with a great hook to keep interest high throughout. Keep up the great writing!
