Ella

Ella is a character in Mass for the Dead, the mobile game set in the world of Overlord, and a member of the Mercenary Knights, where she is the fifth oldest of the sisters and the inventor of the group. She is an elf with long blonde hair down to her shoulders, a green top hat frilled at the brim and a white tunic with tasseled epaulettes, and she sits in a cushioned wheelchair fitted with various implements. Her devices lean toward science and steampunk rather than magic, and most of them come out of her experiments with Remnant, the substance she manages for the group. She is curious, observant, and open about recognizing talent in others, and she keeps her inventions from outsiders in case they are turned against her sisters. When Aggresiel and Billiophia are away, she is the one who keeps the peace among them.
