Here is an extract about this interview :
I once read in article in some sci-fi collection of short stories
that had an interview with RZ where he answered a number of questions
about Amber. In the article it was said that Greyswandir had once been
a
spikard in the possesion of Dworkin at the time he drew the Pattern.
It's presense, as well as the presense of two other Spikards were kind
of responsible for the creation of the reflections of the 3 diffrent
Patterns in Amber, Rebma and Tir. This is where Greyswandir's
connection
with Tir comes from.
Thank you for all and happy new year !!!
