But tieflings look like devils. Therefore, they are. Right? Devils = Evil. Therefore, tieflings = evil.
JK! JK! NOT IN THE FACE! NOT IN THE FACE!
:P
As for dragons:
Red or Blue Dragon Wyrmling has Int 12 (+1).
Average Human Int? 10 (0)
Black Dragon Wyrmling is 10 (0).
Green Dragon Wyrmlings have 14 (+2). Whoa! Why Green Dragon Wyrmlings be so smart? Dang! Even as kids, they're super smart. Green Dragons are the kings of dragonkin. I thought it was the reds. Maybe they're just the scholars and teachers.
White Dragon Wyrmling has 5 (-3). Lol. So White Dragon Wyrmlings are okay to kill. They're stupid. They're not much smarter than animals.
