Season 3 came with a NEW guided games emblem, in addition to the old one. When you complete a guided raid or raid lair as a guide, you get the new emblem and the two-week aura, it looks like a white/off-white star field. It tracks stuff too. The base emblem without ornaments, iirc, tracks the number of Leviathan encounters successfully completed as a guide. It has ornaments, one of which looks like the original guided games emblem. The ornaments may let it track something else, I'm not sure. If you keep it active by successfully guiding, it gives you one free prototype engram per week.
