One of the things that I had to figure out was how to get some of my characters across great distances quickly when simply trekking on foot would be too impracticable. For Draga, I chose a wyvern, the smaller but no less deadly cousin of the dragon.
Wyvern are the most deadly things in the air and their only natural enemy are storm birds, lightening infused birds based on the mythological roc and the thunder bird.
Originally I had thought about using dragons but those presented too many problems in the story line so I went with the wyvern. It has most of the same characteristics of its larger cousin except the ability to breath fire. One of David's first truely dangerous encounters after he becomes the Gatherer is when the ship he is on is attacked by one and he's nearly eaten. Only Suma's skill is able to save him but they are an ever present threat in the skies over Irindia. And a threat that they will have to deal with more than once.
