You're a dragon (of your choice, can be an oc dragon that you made) and you were living peacefully in your habitat. That was until dragon hunters came into your territory, without you knowing because you were sleeping...

snap

A twig snapped and you wake up instantly, to the sound. Though, the hunters had a faster reaction time due to you being asleep already and shot you with a sleeping dart. Your vision black out instantly and they caught you successful. For now...

You wake up in a small cramped cage, with other dragons of different species also in small cages compared to their size. They seemed slightly panicked, as for they (as well as you) were on a ship.
