There are 12 spheres in opposition. It's implied Kralkatorik's second sphere is Air and Jormag's is Spirit.
But that still leaves Bubbles and Primordius
Crystal - Bubbles1
Air - Bubbles2
Fire - Ice
Primordius2 - Spirit
Plant - Death
Mind - Shadow
Which part of Kralkatorik is opposed by water and which part of Primordius by spirit/emotion?
