Meraxes was a great dragon that lived during the War of Conquest and reign of Aegon I Targaryen, the first king of the Seven Kingdoms.
She was the middle dragon, smaller than Balerion, but bigger than Vhagar. Its scales were silver, and her eyes golden.
Along with Balerion and Vhagar, the beast was one of the main weapons used by Aegon in his conquest of Westeros. Meraxes was ridden by Aegon's younger sister-wife, Rhaenys Targaryen.
She died during a campaign in Dorne over Hellholt, where it was shot in the eye by a scorpion, and her and her rider, Rhaenys, met their demise. Meraxes’ skull was later sent to King's Landing, where it is kept.
