While chilling near Ikora Rey, she said in her passive random dialogue "Did you lose a VIRIDIAN engram in the wild?" Is this a hint at a new, top level engram/gear level? The reason I ask is in for example Borderlands 2, after orange/gold level gear (non DLC, orange/gold is the highest gear available), in the DLCs the next highest/rarest level gear was turquoise/viridian. This is just idle speculation, but I thought it was an odd comment for a significant NPC to randomly say. Does something need to be discovered/accomplished to find a VIRIDIAN engram? Or is it just a tease.
