Draco spawned in Cario City alongside Qiong Qi, Roma and Rila. Unlike his usual form, he was disguised as Drake, furthermore his status bar was displayed as that of an NPC.
Draco wasn't foolish enough to appear in a player populated city with three things that shouldn't be accessible to players yet, or even have crossed their minds.
A mount, an NPC servant and a child. Allowing players to see him with all three would bring their minds down to the matter and realize that it was possible to achieve these things.
Draco had a few theories on what might happen at that time, but the most likely outcome was that it would trigger a strong butterfly effect which would ruin things.
