As noted at The Tékumel Foundation website, Professor Barker has passed from this mortal realm. I never had the pleasure of meeting the man in person, but his passing is still a bit of a shock to me. Later today, after doing the necessaries around the house, I will remember the Prof in the only way I can: by starting to re-read, for the uncountable time, his first novel The Man of Gold, pore over his army lists and magazine articles, and maybe even put a little paint on some of the Shén miniatures waiting patiently on my desk. It is the only way I can honor the man - by keeping a tiny part of his legacy alight.
Thank you Professor Barker, for sharing your creation with all of us.
