I'm currently reading The World of Ice and Fire, essentially a "behind the scenes" for ASOIAF, and while reading the section on the Dance of Dragons, I noticed something that confused me.
On page 81, when detailing the dragons involved in the Dance, the book says
Vermax (Prince Jacaerys): Young but strong, killed with his rider at the Battle of the Gullet
Tyraxes (Prince Jacaerys): Young but strong, killed at the Storming of the Dragonpit
Clearly, these two dragons contradict each other in terms of who owns them as Jacaerys was killed with Vermax. This means that Tyraxes doesn't have an owner, according to the book.
I am assuming that this is an error, so who actually owned and rode Tyraxes?
