The SIVA are coming! Shortly after the 2.4.0 update went live, I went exploring. Checking locations on Earth and public events. Then our fireteam came across a SIVA infection in the Fallen S.A.B.E.R. strike on Earth. The location is after entering the mine, clear out the first room. After that head towards your objective. You will find the SIVA inside the tunnel with electricity and the relic.
