1] wishing to escape wolves, Thorgal falls into a deep crevasse.
2] The fall knocks him out . He wakes up in a huge garden. Sisters Ingrid and Ragnhild , mistresses of these places , the host . Thorgal discovers that the garden is an enclosed area where time is slowed by 10 ( one year in the garden = 10 years in real life ) .
3] Thorgal was unconscious one day ( five o'clock shadow ) . But the sisters announce that it is equivalent to a year on the surface of the Earth. Thorgal Skadia meeting , the third sister in the garden. It offers Thorgal to escape with her. Thorgal accept .
4] Skadia says the slowing of time is a lie of her two sisters. Thorgal and Skadia ( and Loki the cat ) undertake underground tunnels back to the surface.
5] After passing through a maze of ice, they finally reach the open air.
6] They sleep and waking , a big surprise awaits Thorgal : Skadia is as old died of a sudden . Ingrid and Ragnhild were true . Leaving the garden, caught Skadia time , making him take 150 years at once.
A question: having lived all his life in the garden, Skadia had to know how many years it went through. So she must have known she was 150 years. Why she continued to believe in before 15? And another thing, thinking: 1 year = 365 days. 365/10 = 36.5 days. Year remained unconscious in the garden, is 36.5 days in the real world. A small error of proportionality was committed here. The author seems to have concidere things like this:
30 => 300 years
25 => 250 years
15 => 150 years
1 day (normally 36.5) => 1 year
