Sayd is a fictional character in the DC Comics universe. She is now an exiled member of the Guardians of the Universe. Where most of the Guardians are void of emotion and rigid in their compliance to standard policy, Sayd's sensibilities are more in line with those of Ganthet, a Guardian known for his non-traditional mindset. The two are exiled (in part) for their love for one another.
In Green Lantern #150 Kyle Rayner (as Ion) relights the Central Power Battery on Oa and restores the dead Guardians to life. However they were restored as children in a mix of male and female instead of adult males (their original forms). Sayd was one of the reborn members of the Guardians of the Universe, and one of the six female (out of twelve total) members of the organization.
Sayyid (also spelled "Seyd", "Syed", "Sayed", "Sayyed", "Saiyid", "Seyed" and "Seyyed") (pronounced [ˈsæjjɪd], or [ˈsæjjed], Arabic: سيد; meaning Mister) (plural Sadah Arabic: سادة, Sāda(h)) is an honorific title denoting males accepted as descendants of the Islamic Prophet Muhammad through his grandsons, Hasan ibn Ali and Husayn ibn Ali, sons of Muhammad's daughter Fatimah and his son-in-law Ali (Ali ibn Abi Talib). Conventionally, descent is patrilineal. However, in 1632 when an Ottoman court challenged a man wearing a sayyid's green turban he established that he was a sayyid on his mother's side, and this was accepted by the court.
Daughters of sayyids are given the titles Sayyida, Alawiyah, or Sharifa. In some regions of the Islamic world, e.g., India, the descendants of Muhammad are given the title Amir or Mir, meaning "commander", "general", or "prince". Children of Sayyida mother but a non Sayyid father are referred to as Mirza.
In the Arab world, it is the equivalent of the English word "liege lord" or "master" when referring to a descendant of Muhammad, as in Sayyid Ali Sultan. This is the reason the word sidi (from the contracted form sayyidī, 'my liege') is used in the Arabic.
