  We introduce quantum skein relations for a family of ribbon categories
parametrised by the projective plane over $\bQ$.
  There are thirteen points for which the ribbon category admits a ribbon
functor to a category of invariant tensors
  for a quantised enveloping algebra. These thirteen points lie on three
projective lines. One line gives the first
  row of the Freudenthal magic square and another gives the fourth row which is
the exceptional series.
