However, the dragon breath rules are not at all similar for the half-dragon and the dragonborn, and I've also noticed wiki article that imply that they are different races entirely. I had assumed that when writing the adventure they were only allowed to use known material from Basic, and so renamed the Dragonborn into 'Half-Dragon' for the sake of compatibility etc. In the Hoard of the Dragon Queen adventure, for example there is a Half-Dragon npc.
What are the differences between 'Dragonborn', 'Half-Dragon', and 'Draconian' races in D&D?
