How do I sell off my 5 years old Warcraft III Demon / Corrupted / Naga / Draenei Text Project to Blizzard-Microsoft for money?

I got the ideas all set for the Demon, Naga, and Corrupted races in text schematic forms, while I am still working on the Draenei race to complete it... These ideas are either for Warcraft III: Reforged, or maybe for Retera's Warsmash game... But, how do I sell off these God-Christ-inspired ideas without my ideas being stolen, and where?? And even then, how much can I get out of my 5 years of text work for the 4 new Ladder races for Warcraft III? How do I get these copyrighted?

Please help me guys, if you can... Thank you very much in advance...
