Jiglad Wert was a powerful wizard during the events of The Light Fantastic and leader of the Brotherhood of the Hoodwink. He lived in his own tower at the Unseen University. He had in the past taught aspiring student wizards, including Trymon and Rincewind, proclaiming Rincewind's magical ability to be somewhere less than zero.
As head one of the eight orders, Wert held a seat on the University Council. He disagreed with Trymon's plan to employ a hero to locate Rincewind, as wizards and heroes have seldom got on -a lot of comments are made about each other’s dress sense, heroes' inability to read without moving lips, wizards' being 'scared' of women - usually leading to a fight).
Wert was forced to agree to the plan when Trymon pointed out that magic had proved ineffective and that some unknown force was concealing Rincewind from them.
When Trymon was taken over by the magic he had unleashed in reading the Octavo, Trymon’s first act was to turn Wert and the other Heads of the Orders of Wizardry to stone atop the Tower of Art and proclaim himself supreme head of the orders. While Rincewind was able to stop and defeat Trymon, nothing could be done to restore the petrified wizards who became statues in the garden. Unfortunately for Wert, his statue had been dropped by the workmen and about all the pieces were good for, according to Rincewind, were to be made into a nice rockery by the gardener.During his disputes with Trymon, he questioned Ymper Trymon about the chair, previously belonging to the late Galder Weatherwax, which Trymon had burned in the following dialogue:
- Jiglad: "What happened to old Galder's chair, the one with the lion arms and the chicken feet?"
- Trymon: "That? Oh, I had it burnt."
- Jiglad: "Burnt? But it was a priceless magical artifact, a genuine–"
- Trymon: "Just a piece of junk, I'm afraid. I'm sure real wizards don't really need that sort of thing. Now, if I may draw your attention to the business of the day–"
- Jiglad: "What's this paper?"
- Trymon: "It's an agenda, Jiglad."
- Jiglad: "And what does a gender do?"
- Trymon: "It's just a list of the things we've got to discuss. It's very simple, I'm sorry if you feel that-"
- Jiglad: "We've never needed one before!"
- Trymon: "I think perhaps you have needed one, you just haven't used one."
- Jiglad: "Well, all right."
