At one point David Hargrave published something known as the Arduin Chronicles. Typewritten and chock full of information, it was a handy and useful Arduin reference. This rhyme is but one of many things he shared with fans. As it is all but lost to time, I'm reposting it here for everyone to enjoy.
Blue slim staff, red glow summit
Keeps all of the evil, fairly from it.
Yet again and more its powers are,
Ranging close, and travelling far.
Wang's it was, Thakk's it is now,
But even more guarded it is, by another's vow!
The ogres four, no less and no more
Point the way to the one true door.
