Risa T’Kerix

Risa T'Kerix is an asari Spectre, and one of Shepard's security detail.
Risa has a calm, but dangrous presence- she reminds Garrus of Liara's father, Matriarch Aethyta. She was the senior Spectre assigned to Garrus' mission to become a Spectre himself. She's not much for the normal small-talk, but will happily talk shop with competent people.
