Remnants are a Race in Mass Effect Andromeda.
"Remnant" is the umbrella term coined for technology, structures, and autonomous bots that have been sighted across the Heleus Cluster. Seemingly abandoned by whomever created it, this Remnant technology is extremely advanced, but most of it is in a "standby" state. On Habitat 7, Alec Ryder discovered that reactivating this technology requires scanning "glyphs"-data packets written in Remnant coding language-and my assistance with "interfacing" at particular consoles.
This is complicated by Remnant bots that still guard and maintain many of these installations. Remnant bots do not appear to be sentient, but they are programmed to consider any interference with their technology as a hostile act and attack single-mindedly.
The kett have an interest in Remnant technology, and have been sighted across the cluster attempting to study or control sites where it is still active. Evidence suggests the kett have not yet developed a reliable method of interfacing.
