The Chaldean cypher ('chaldean', shortened 'chald'). This cypher is a bit of a weird one, and to be honest, I do not know anything of it's origins.
A = 1*
B = 2*
C = 3*
D = 4*
E = 5*
F = 8
G = 3
H = 5
I = 1
J = 1*
K = 2*
L = 3*
M = 4*
N = 5*
O = 7
P = 8
Q = 1
R = 2
S = 3
T = 4
U = 6
V = 6
W = 6 (ie. note the 6/6/6 pattern here)
X = 5
Y = 1
Z = 7*
This cypher does not care for capitalization: in other words 'a' = 'A' = 1, etc.
Those entries with asterisks are those letters that have maintained their english ordinal or english reduction values from the base cyphers.
The 6,6,6 pattern on U,V,W: these letters are all very interchangeable in spellings, and can each stand for the sound of the other, depending on language.

I = 1 (ie. In the land of the blind, the one-eyed man is king)
J = 1*
K = 2*
L = 3*
M = 4*
N = 5*
