After bonding the mate bond has been established, Jacob is dominant in their relation while Fynn is Submissive. Edward is dominant for Fynn and Submissive for Jacob. Edward has found his family (cullins) and apologized to them for everything. They forgave him and happily moved to castle with them.
After being in healthy relationship for a year, Jacob proposed his both mates on Fynn's birthday.
Jacob has taken permission from Fynn's father (witch king) and Alex (Fynn's guardian). For Edward Jacob has taken permission for remaining Cullins and also Bella's father. Since both Edward and Jacob respected Charlie like father and Jacob thought by getting permission from Charlie will give Bella's soul some peace.
Both Fynn and Jacob happily agreed to marry Jacob. They got married in closed family ceremony. But after marriage the party was grand affair. All supernatural species wanted to be part of celebration, so it was decided each species will have a day in neutral kingdom to celebrate. All species, their lords, families, council members came on respective dates given to them for functions and feasts. It took whole week of celebrations.
After some years the trio discussed about children. Jacob suggested instead of adopting a child they can set up orphanage like human world. All species orphan children or outcast can be taken in the orphanage and given a chance to better life. Edward and Fynn agreed to idea. They set up big orphanage in neutral zone. Also they informed allies about it. If for any reason there is any child whose family doesn't want him or child doesn't want to be with his family, the child is always welcome in orphanage. The decision are taken after careful analysis of situation. Their is teacher from each species as different species children has different requirement. Things improved a lot and law and order was established in supernatural world.
After a century of peaceful and progressive ruling, one day Fynn told his mates that he wants to give up his powers and grow old, so he can die peacefully. For Jacob and Edward it was not possible to change their powers so they didn't like the idea. Fynn explained they how he never wanted immortality in first place. He is happy with his life and he thinks his purpose is fulfilled. He is happy with everything but he is tired of being immortal. Finally they accepted Fynn's decision and allowed him to do with heavy hearts.
After twenty five years from the moment Fynn gave up his powers he died. He promised his mates that he will wait for them in afterlife and asked them to live their life happily till that moment.
After Fynn's death Jacob's wolf got very weak. Jacob's love for Fynn was from his school days. No matter how much he tries with every moment he sees Fynn in it. Sometimes Jacob felt sorry for his Ed, because Ed was trying so hard for Jacob to smile. Jacob tried very much for the sake of Edward but his wolf stopped speaking. Jacob now thinks same way as Fynn did, he wants to rest in peace for ones and all. After six month Jacob also died saying same words to Edward that Fynn told them. For Edward now immortality is curse then boon without both of his mate. Although Fynn was his real mate Edward was more in love with Jacob than Fynn. Jacob's warm hug was giving his cold heart reason to beat, but with Jacob's death Edward is now wanting nothing more than death itself.
He asked his family to kill him but no one agreed. Edward asked Alex knowing ones he takes Fynn's name Alex would agree to it. A month after Jacob's death Alex killed Edward with wooden stick as per his wish. Edward's last words were thank you with a big smile on face. Alex said hope this will put you at peace and reunite you with your lovers.
