I was having a conversation on Facebook and I decided to dig up an old crossword puzzle about Zelazny I had created back in 2015.
Unfortunately, when I returned to it, I found that I made it mostly as a joke, what with answers like Melbriniononsadsazzersteldregandishfeltselior and Kjwalll'kje'k'koothai'lll'kje'k. (I'm surprised that I found the restraint to avoid throwing Strygalldwir in there too.)
So here is the link to a revised and updated version of the puzzle. It's challenging, but all the answers are readily available online if you google around a bit.
