Annael was a Sindarin elf who lived with his people in the caves of Androth in the region of Hithlum called Mithrim, in northern Beleriand in northwestern Middle-earth. He was known for fostering Tuor in his youth.
Annael was mentioned only shortly in "Narn i Chîn Húrin", the Tale of Húrin's Children, as the caretaker of Tuor, son of Huor, a Man of the House of Hador, after his mother Rían sent him there. Rían then went northwards to the Haudh-en-Ndengin, the Hill of the Fallen, where her husband Huor had fallen in the fifth battle of Beleriand, the Nirnaeth Arnoediad, and she lay down and died.
When Tuor was sixteen and able to fight, he desired to avenge the suffering and death of his people by the enemy but Annael restrained him from any rash action. Instead, Annael told him of his peoples' intention to leave the caves and escape into the south through the Gate of the Noldor, and it was from here that he first learned of King Turgon and Gondolin.
When Annael's people left Androth, they were ambushed by a force of Easterlings under their chief Lorgan, and they took Tuor a slave. Annael survived the attack and he and his people eventually came to Círdan in the southern part of the Beleriand. His fate is unknown.
