Lyman Beesbury

Lyman Beesbury is an unseen character in Game of Thrones. He is long dead before the start of the series, and thus is not expected to appear. Lyman Beesbury was the head of House Beesbury and a member of the Small Council prior to the Dance of the Dragons.

Background
Lord Lyman was a member of the Small Council under Viserys I Targaryen. When King Viserys died and Ser Criston Cole of the Kingsguard plotted to crown Viserys's son instead of his daughter and designated heir, the aged Lord Lyman protested, prompting Ser Criston to kill him before eyes of the entire council.

In the books
In the A Song of Ice and Fire novels, Lyman Beesbury is never mentioned. He appears, however, in The Princess and the Queen short story. Lord Lyman was Lord of Honeyholt and the Master of Coin during the reign of Jaehaerys the Conciliator and also under Viserys I, as replacement of Prince Daemon Targaryen. He was eighty when Viserys I passed away. When the small council met to plot crowning Prince Aegon, Viserys's eldest son by his second wife, over Princess Rhaenyra, Viserys's designated heir, Lord Lyman soundly protested even though he was outnumbered. Ser Criston Cole silenced the discussion by slitting Lord Lyman's throat with his dagger. He was replaced as Master of Coin by Ser Tylan Lannister, the Master of Ships.
