Drakes are humanoid and have long tails. They consider their tails to be private body parts, and it is considered erotic to touch a drake's tail. Erin Solstice once pulled Olesm to safety by tugging his tail, which caused him to blush furiously and send Erin some very strange glances afterwards.
Drakes are descendants of Dragons. Many drakes share a very strong hatred to Lizardmen, although the distinction between Lizardmen and Drakes is unclear, because no lizardmen have been shown yet in the story.
Culture
In addition to viewing tails romantically, they have any customs regarding their tails.
Drakes don't seem to use stick-man symbols to symbolize gender-intended restrooms. Instead of it, they use tails; a straight tail refers to the men's room, whilst a curly tail refers to the women's room.
Another Drake tradition revolving tails is their marriage customs: proposal among drakes is done by placing a ring around the tail of the drake you wish to marry.
