Yes, there is just one Jormag. They is often used in English to refer to people without distinguishing between genders (for example when you don't know what gender the person you are referring to may be). So as an example, I would say over the internet about someone who's gender I don't know, they like GW2, instead of he/she likes GW2. Ah okay I think I might understand. When I learned English, I was told "they" is always plural, and neutral singular was "it". But thank you for the explanation. Why not use "it" since Jormag is a dragon is also confusing to me. But thank you.
