I had drawn up a shortlist of who would be the first person to point out to me that Gamling was in the books. I did not choose correctly....
Nevertheless, he is a completely different character, with a different age, and a different role. He counts as an invention with a name from the books.
Now, I haven't been on any official sites, but can you guarantee that those were two different characters, one called
Mablung and one called
Madril? If true, I did not notice.
