Though most of the nobles that entered Grenton died, some actually survived. These people were the ones who had no more intention of getting Valdel's weapon. After learning that Valdel had a ring with the emblem of the royals, these nobles decided that the risk of offending Valdel was too much for them to handle, so they left the town as quickly as possible.
At this point those that left early didn't know how lucky they were. The nobles that died in Grenton were eight in total. News of their deaths will be known to the public after a few days. The king who heard the news from one of his subordinates, didn't bother hearing the pleas of the family of these nobles, and simply called them traitors. After branding their family as traitors the king needed to wipe out the whole family lineage, since they already were in such a state, the chance of them revolting against the crown was high. So before they could do that, the king went ahead to exterminate future threats to the royal family.
