Baeron Pyke was the Master of Coin under King Harys Baratheon.
Baeron was born of an unknown member of House Harlaw. At the age of sixteen, he apprenticed under King Renly Baratheon's Master of Coin, and when the man died he was raised to the position himself.
It was assumed that Baeron died during the Sack of King's Landing.
The new Master of Coin, Lyman, discovered that Baeron had been skimming money from the crown's coffers for the last six years of King Harys Baratheon's rule. He had amassed nearly 800,000 gold dragons before his 'disappearance' during the Sack of King's Landing.
