Saga one is unlocked in floor 1 - 11 so Frozen
Saga 2 comes 12 - 17 aka Abandoned
18 - 29 is the furnished floors (not exactly but mostly)
30 - 35 - saga 3 in abandoned 2
Um, according to the news item it's floors 1-11 for the bearskinpelt, floors 12-21 (aban1 + some furnished) for the collection of swords and floors 30-40 (aban2 + some occult) for the scribbled notes. Is it wrong?
