Allayn Yairley was a Charisian citizen and an officer of the Royal Charisian Navy.

Yairley was born in the Kingdom of Charis and had one younger brother, Dunkyn. Both joined the Royal Navy and persued an officer's career. Dunkyn chose to serve on a merchant galleon for two and a half years, as he considered the service to look good in his record, while Allayn sought the command of a galley.

In the long run, this kept him from receiving command of one of the kingdom's new war galleons as early as his younger brother. (BSRA)
