True Identity:

Spoiler

Lancer serves as the Servant of Kayneth Archibald El-Melloi during the 4th Holy Grail War. Lancer is generally even-tempered and absolutely loyal to his Master. He is known for his chivalry and sense of honor, which contrasts with Kayneth's arrogant personality. He shares a bond of mutual respect with his rival Servant, Saber, and his greatest wish is to face her in fair combat.
Kayneth Archibald El-Melloi summons Lancer in the 4th Holy Grail War, having originally intended to summon the Rider-class Servant, Iskander. Because his pupil Waver Velvet stole the artifact Kayneth had meant to use as a catalyst, Kayneth summoned Diarmuid Ua Duibhne in Iskander's stead. Lancer's contract with Kayneth is unique in that, while Kayneth holds the Command Spells, the energy to materialize the Servant is maintained by Sola-Ui, Kayneth's fiancée.
