Numbers not necessarily canonical
On the 12th day of Carpmas, Garth Nix bestowed on me:
12 Nithlings swarming
11 Piper's children
10 Paper Pushers
9 Rats a-sailing
8 sorcerous doctors
7 Trustees sinning
6 augury boxes
5 strom lanterns
4 Times of Day
3 sunships
2 Not-horses
And the House that rules all the cosmos
And a sentient flying eyebrow
Actually, I stopped worshipping the Carp after it and its confederates destroyed the House, but Wednesdaymas didn't fit the rhythm.
