human
[LotR] shaddow of mordor

played the game a few months back. and i was just wondering if Celebrimbor was an actual character from any of the books? like did he help make the ring of power? or was it just for the game ?
gpt
He certainly was a character, and yes he did help create the human and dwarves rings. He made the 3 elf rings in secret in spite of Sauron. And Sauron took the knowledge of ring-making and forged the one ring in secrecy as well.

However, as good as Shadow of Mordor was (I absolutely loved it) it is just glorified fanfic, there is no record of Talion, the evil lieutenants of Sauron, or that Celebrimbor had his family murdered in front of him and led an Orc army against Sauron.
