I don't know how to implement it but my idea for this now is to dye the normal story kinda but a little off with him doing his own adventure but still involves with the original plot until after the tournament and the war starts between the church and the clans. After that I think maybe he helps manage the city Shrek is in while the war is going on and helping when needed but who knows I might change this so pls tell more something to add or something you would want the direction it should go in or whatever reason
Thanks
