In Greek mythology, Endeïs was the wife of King Aeacus of Aegina and the mother of the heroes Telamon and Peleus. Because Peleus fathered Achilles, and Telamon fathered Ajax the Great and Teucer, Endeïs was grandmother to all three. Ancient sources disagree about her parentage, naming her variously the daughter of the centaur Chiron, of Pandion of Athens, or of the Megarian Sciron.

I.Etymology
The name Endeïs is explained as a dialect variant of Engaios (Ancient Greek Ἐγγαῖος), meaning "in the earth."
II.Family
Endeïs's parentage varies across the ancient sources. She is described either as the daughter of the centaur Chiron and the nymph Chariclo, as the daughter of Pandion of Athens, or as the daughter of Sciron, a Megarian warlord.
According to some accounts, her father Sciron arranged her marriage to Aeacus after Aeacus appointed Sciron as the military leader of Megara.
By Aeacus, Endeïs was the mother of Telamon and Peleus. Through these sons she became grandmother to Achilles, the son of Peleus, and to Ajax the Great and Teucer, the sons of Telamon.
III.Mythology
Endeïs harbored hatred toward her stepson Phocus, the son of Aeacus by the Nereid Psamathe, and wished for his death.
Her own sons Telamon and Peleus likewise resented Phocus, possibly out of jealousy of his athletic prowess. The two drew lots to decide who would kill him.
Telamon won the lot and slew Phocus during a pentathlon by hurling a discus that struck him a fatal blow. After the hidden body was discovered, Aeacus exiled both Telamon and Peleus from Aegina.
