Lallafa was an ancient poet who lived in the forests of the Long Lands of Effa. His home inspired him to write a poetic opus known as The Songs of the Long Land on pages made of dried habra leaves. His poems were discovered years after Lallafa's death, and news of them quickly spread. For centuries, the poems gave inspiration and illumination to many who would otherwise be much more unhappy, and for this they are usually considered around the Galaxy to be the greatest poetic works in existence. This is remarkable because Lallafa wrote his poems without the aid of education or correction fluid.
The latter fact attracted the attention of some correction fluid manufacturers from the Mancunian nebula. The manufacturers worked out that if they could get Lallafa to use their fluids in a variety of leafy colours in the course of his work, their companies would be as successful as the poems themselves. And so, they traveled back in time and beat Lallafa until he went along with their plan. The plan succeeded, Lallafa became extremely rich, and spent so much time on chat shows that he never got around to actually writing The Songs. This was solved by each week, in the past, giving Lallafa a copy of his poems, from the present, and having him write his poems again for the first time. But on the condition that he make the odd mistake and use the correction fluid.
Some argued the poems were now worthless, and set out to stop this sort of thing with the Campaign for Real Time (a play on Campaign for Real Ale), or CamTim, to keep the flow of history untampered by time travel. Slartibartfast is a member of CamTim. (The necessity for this campaign is contradicted by other events in the novels. For example, when Arthur Dent and Ford Prefect landed on primitive Earth, they decided that nothing they could do would change history. And when Agrajag diverted him to a Cathedral of Doom to try to kill him, Arthur Dent's perpetual victim said that he'd try to kill Dent even if it's a logical impossibility, Dent not having ducked a bullet yet.)
Lallafa appears in the novel Life, the Universe and Everything and fit the fifteenth of the radio series.
