Meaning: The Clans must find SkyClan, the fifth lost Clan (what you find in the shadows), and bring them back to the lake territories in order to stop Darktail and allow them to reclaim their rightful place among the Clans around the lake (clear the sky), restoring the original five Clans (embrace).Alderheart initially thinks that it refers to Violetkit and Twigkit, because they were found among the shadows of a tunnel where Sandstorm's spirit leads them, though it was revealed later that Twigpaw is the one fated to bring SkyClan to the lake.
Meaning: All five Clans must use their signature skills, related to their Clan names, in a combined strategy to defeat Darktail and his rogues once and for all and recover ShadowClan territory: climb and hunt in trees (SkyClan), brute strength and attack power (ThunderClan), speed (WindClan), hiding in shadows and sneaking through undergrowth (ShadowClan) and swimming (RiverClan).
Meaning:Rowanstar's plans to dissolve ShadowClan and make the remaining cats join SkyClan, giving up their territory, must be stopped and ShadowClan needs to be restored, because there has to always be five Clans. Also, most of the ShadowClan cats found themselves unable to accept the situation or assimilate into SkyClan and their opinions clashed constantly with those of Leafstar and the rest of SkyClan cats, causing friction between both groups and giving the impression that they were de facto two Clans sharing one camp, instead of only one Clan. After Tigerheart was resurrected and made the new leader of ShadowClan by StarClan, the newly restored Clan returned to their old camp and territories, leaving SkyClan and avoiding more inner conflicts with them, thus ending the "dark sky" and restoring the number of Clans to five once more.
Meaning: The Clans needed the help of Tree, a loner who had six toes on one of his hind paws and the power to summon the spirits of deceased cats in order to stop the "coming storm", the imminent dissolution of ShadowClan and his merge with SkyClan, that threatens to disturb the lake's balance, because the Clans must be five to continue existing.
Meaning: The other Clans must accept SkyClan and split territory equally to make room for them and avoid disputes in the future. This allows the five Clans to become a democracy and finally live in unity around the lake, marking the beginning of a peaceful era.
Meaning: Lightning will strike the RiverClan camp, causing a dangerous fire that will burn down the camp and force RiverClan to flee into the other Clans' territories seeking help and refuge, thus ending their isolation and reuniting them with the other Clans; Twigpaw initially fears that it could be the ThunderClan camp, because she couldn't identify the burning camp as a result of the fire damage. Yellowfang was merely trying to scare Twigpaw in order to wake her up, because she sneaked into the Moonpool and intruded into StarClan territory without permission, although the apprentice misinterpreted the warning at first and believed that Yellowfang was telling her that she didn't belong in ThunderClan.
Meaning: If a Clan falls, the other four will fall as well. Specifically, it refers to SkyClan, which was at risk at the time of being kicked out of their territory by ShadowClan. Ultimately, all the Clans decide to shift their borders in order to make space to SkyClan, allowing them to finally live together in peaceful unity at the lake.
