Dragonkeepers were stationed both at the Dragonpit in King's Landing and on Dragonstone. The Dragonkeepers at King's Landing numbered seventy-seven men during the reign of King Jaehaerys I Targaryen and during the Dance of the Dragons.
The Dragonkeepers wore suits of gleaming black armor. Their helms were crested by a row of dragon-scales that continued down their backs, diminishing downwards.
In 60 AC, as Princess Daenerys Targaryen was stricken by the Shivers, King Jaehaerys ordered a raven sent to the Dragonkeepers on Dragonstone, ordering them to bring a hatchling to King's Landing at once. After Daenerys died several hours later, Jaehaerys flew to Dragonstone upon Vermithor to inform them that it was no longer necessary.
According to the accounts of the Dragonkeepers, when Princess Alyssa Targaryen came to claim a dragon in the Dragonpit in 75 AC, they had to convince her not to claim Balerion, telling the princess the dragon was "old and slow" and suggesting she would rather have a swifter mount. In the end they succeeded, as Princess Alyssa claimed the dragon Meleys.
Once, when Princess Viserra Targaryen brought six boys into the Dragonpit, promising her maidenhead to whoever would put his head in a dragon's mouth, the Dragonkeepers arrived in time to put an end to it.
During the Dance of the Dragons, less than fifty Dragonkeepers stood guard the night when a a rioting mob stormed the Dragonpit. The Dragonkeepers fought the mob, but were greatly outnumbered and eventually slaughtered when the mob broke through the many doors of the Dragonpit.
