Ask HN: Are any of you familiar with Sword of Glass' history?

I stumbled upon this review of Sword of Glass, and the mystery surrounding its creation.

The post's author says "Every once in a while, I think on this game. It irks me that we can't seem to find out who programmed it. I consider it one of the great mysteries of CRPG history."

All we know is (mentioned in the blog post):

> The main game executable says "Copyright 1985 Borland Inc." I don't remember seeing Borland associated with the game anywhere else.'

> a piece of software that wasn't offered individually but packaged with dozens of other titles and sold under the banner "100 FANTASTIC RPG ADVENTURES!" or something'

A thing I find very interesting about the game is the way to add another player to the party, and how it essentially duplicates the UI allowing another player to explore alongside.

I thought I'd ask on HN, as he hasn't made any progress on learning its origins, and this seems like a nice place to ask.
