Avina is a virtual intelligence program designed to answer questions and provide guidance and insight on current events, and within Mass Effect, Mass Effect 2 and Mass Effect 3, is found on the Citadel.

Avina appears as a hologram, always taking the form of an Asari – one of the races found in the Milky Way Galaxy – and will be accessible at several terminals throughout the Nexus in Mass Effect: Andromeda. With a limited capacity for discourse, Avina is suited more to offering information than giving opinions.
