Possible skin coming this Chapter?spotted by: @FortniteBRFeed https://t.co/rF0CSKhvC2#FortniteThe trend of finding Easter Eggs has been around ever since the video game developers started incorporating and hiding them in-game. But in Fortnite, a battle royale where traditional players least expect it, flipsiders seem to find it even more than any other game and start making their own speculations. Earlier this season, players found an Easter Egg from a crashed refrigerator in Condo Canyon that refers to an Indiana Jones movie scene.The mysterious 'SL' in a lone islandYesterday, a player found an interesting Easter Egg near The Sanctuary POI on a Lone Island in the Fortnite Map. Interestingly, the island's beach writings show the letters 'S' and 'L' drawn on sand. Since then, the community has started speculating what it means, and the responses have been quite insightful.A Redditor commented that the 'SL' might suggest Sister Location. This refers to the Sisters that Agent Jones spoke of to The Foundation during the Zero Crisis Finale that he can get him to them. Since the event, players have been waiting for answers on who the sisters are and when they will make their appearance in Fortnite.SINGULARITY.@ZEROSDEFENDER&&. in other news, since this is more relevant in the fortnite community than we think, i think we should consider making this into an SL?11:28 AM · Jan 6, 20225&&. in other news, since this is more relevant in the fortnite community than we think, i think we should consider making this into an SL? https://t.co/Pn7OCnQY4rAnother player shared his idea via Twitter that S L might suggest the shapes of the logos of The Seven and Imagined Order. As one can notice closely, the shape of The Seven's logo suggests two Ls joined together and an S in the center of the logo of the IO. This may refer to the war between both factions.Players already know that the big bad agent of the Imagined Order will be making her appearance soon in Fortnite. When they saw Slone earlier featuring in a Snow Suit in January's Crew Pack, and IO Drills spread around the map, speculation rose that maybe someone was writing SLONE on the sand before she arrived in the Chapter 3 map.As the letters 'SL' can be abbreviated from a number of terms such as Seven's Land and Seven's Lore to even meme content like Save Llamas, the player community continues to speculate on what this means.
