Talion

Talion is the famous Gondorian Ranger from the popular game Shadow of Mordor and Shadow of War. Talion had a family and a child that were taken from him by the Dark Lord. Talion was then bound to the soul of Celebrimbor who came back from the Halls of Mandos to aid him in his quest for vengeance. In a long turn of events, Talion/Celebrimbor fuse into one body and begin to craft another ring of power to stand against Sauron himself.

Tolkien's Canon
Since Elves were sent immediately to the Halls of Mandos--and only a select few were reborn (Luthien and Finrod are prime examples), the story of Shadow of Mordor/War doesn't make much sense in the Tolkien Canon. In fact, it outright butchers it.

There is a plausible solution to this however, perhaps in his sensing of what Sauron has done, Celebrimbor crafted his thoughts/memories into his ring. Upon chance while adventuring, Talion finds Celebrimbor's ring that he had hidden in a special spot in Eriador. Talion then gains the memories and thoughts of Celebrimbor leading him to fight against evil with renewed vigor and bearing a ring of power.

This could be a more plausible backstory that would allow Talion to function in Tolkien's work. Since several lesser rings were created, Celebrimbor sent the Three Elvish Rings off and had them hidden, and finally, placing one's thoughts and memories into a ring seems more reasonable for an elf than placing his soul in the ring like Sauron did.
