I guess there is an attribute missing, so that translation would be: "I am [the Son? the Legacy?] of the Dragon." Sounds better, doesn't it?
Ego sum draconis?
Ego draconis [sum], yeah :p Latin doesn't like redondancy(?), so there is a choice between "ego" and "sum" to make. Yet, "Ego Draconis" is a great title in a phonetic point of view
