The people of Alhereth are sad their loved ones did not survive, but are happy the disappearances will stop. They gladly offer you drinks and free boarding for the night. Even Gragor is welcomed. The people of Alhereth hold no grudges, after all his tribes got fooled by a clever Fellgrim, and Gragor tried to be the voice of reason and he almost shared their loved ones fates for this. Plus he helped the party in the end to make things right, and fitch the dwarf merchant is willing to vouch for him.
In the coming few days, a lot happens. First the elves who were looking for Fitch eventually make it to Alhereth and find out from the merchant what was really going on all along. They are a bit hostile spotting Gragor at first, but once again, you all vouch for him. Nobody in Alhereth could decipher the papers the group recovered from old Snake's Demise, so they suggests to perhaps visit the libraries of Menana Mindas in order to have those translated. Still others are troubled by the sights of beastlings and felgrims so far south, especially backed up by tribes of goblinoids and wildlings, and instead insist that nearby Atrhand should be warned. Then there is Fitch, still looking for new carts and retrieving the remaining of his stuff from old Snake,s Demise, who would appreciate if you could escort him to Rith Amdol.
This, is of course, a choice our heroes will make in another story...
