Lion was the Tribal Totem of the White Howlers, the native Scottish Garou who fell in battle with the Wyrm and were consumed by it. Its symbolism is still apparent the the Royal Standard of Scotland - the Lion Rampant - a strong symbol of Scottish pride and national identity. This noble beast was once native to Scotland (and all of Northern Europe) but was subsequently wiped out by the Roman invaders. Many cave paintings and carvings detail Lions and other extinct animals, like in the Wemyss Caves of Fife whose legacy reaches back to the Stone Age.
When the Fianna Elder Seanair Ronnchraos (Grandfather Slavermouth) tried to ressurect the totem of the White Howlers in Kirkcaldy, Fife, he was only partially successful. He, and his noble band of followers did indeed manage to contact Lion, but were unable to awaken the Great Spirit for more than a few minutes. He agreed to act as Sept Totem, but once more fell into his slumber and drifted back to the Deep Umbra.
Fortunately, Lion was not the only spirit to heed the call of Slavermouth. The wily Totem of Cunning, Fox was in attendance, and agreed to act as Lion's Majordomo, commuting his instructions back and forth through the Deep Umbra to where Lion held his Court as King of the Beasts.
The Cairn a Leoghann Caidil, therefore, has two Totems: Lion - strong, fierce and proud and Fox - wily, quick and cunning.
