Unlocked Floo Flames act as fast travel points. To unlock a Floo Flame, simply walk near it. There are 86 Floo Flames in total, but you can only unlock 83 because four Floo Flames are located in the common rooms of each house, one in each, and depending on which house you have selected, you will only have access to one of them.
Once you unlock 83 Floo Flames, you will be awarded the "Floo Around the World" achievement / trophy.
Track undiscovered Floo Flames to unlock permanent Fast Travel locations and shorten the time it takes to reach new activities and locations.
