Encounter at Massey's Hook

The Encounter at Massey's Hook was an event that took place after a failed attempt to tame the dragon Rhaegal, resulting in the deaths of Laenor Longwaters, Berena Tully, and Prince Jacaerys Targaryen, as well as the dragon Cyrax.

The encounter took place during the 12th Day of the Ninth Moon of 407 AC.

Background
Selenya Targaryen, since arriving in Westeros, had been inquiring as to the whereabouts and abilities of Rhaegal, formerly ridden by Prince Aemon Targaryen, who went missing two years prior. Her inquiries led her to the Grand Maester Selwyn, as well as many texts regarding the dragon's behaviour. Selenya made many inquiries as to how the dragon might be tamed, and when the Ninth Moon dawned of 407 AC, sightings were made around Massey's Hook detailing the great dragon in the skies, riderless, having made his roost atop a large hill in one of the many plains of the region.

Departing King's Landing on the first day of the moon with an entourage of her closest friends, advisers and attendants, most notable among those including the peasant Benn, Denya of Braavos, Maro, Laenor Longwaters, Berena Tully, Saera Targaryen, and her deep-seated lover Rhaegar Targaryen, the group arrived at Massey's Hook on the third day of the Ninth Moon.

Further inquiries were made, this time in person, as Selenya Targaryen routinely left Rhaegal venison to feast on, oft risking her own life in the process. On the eleventh day of the ninth moon, Jacaerys Targaryen appeared as well atop his dragon Cyrax. The formidable dragon was a sight for sore eyes in the regards of many, but Rhaegar warned that he was taking a great risk in being there.

During that same evening, Jacaerys sought to formulate a plan with the other present dragonriders, should something go awry. He warned not to approach Rhaegal should the worst occur, and that his own dragon Cyrax, and Rhaegar's own Nightwing, would be able to fell the beast, or at least force him away.

The Encounter
The day began as Selenya Targaryen and her entourage ascended the hill. Of the six who joined her, only three would live to tell the tale. Berena Tully followed far behind the main group, hiding behind a series of boulders for the majority of the encounter. Benn and Denya remained shortly behind Selenya, while Saera, Rhaegar, and Jacaerys had taken to the skies.

Selenya's attempt to tame Rhaegal had been aided by several key factors, but the beast would have none of it. As Selenya knelt before him in the midst of his roost, Rhaegal bathed the Lady Selenya in flame, then whipped his tail towards her, knocking her unconcious.

Rhaegar Targaryen flew down on Nightwing almost immediately after, in hopes of distracting the great beast. Denya also made attempts to distract him, but failed.
