Normally I’d say you shouldn’t capitalize land, but it worked for Stephen R. Donaldson, didn’t it? If Land is the real, proper-noun name of the place, yes, capitalize it.
Next we run into a problem with verb tenses… If the place is important, you should say that many go there: present tense, not past. If they went there, you should say it was important. Or have gone, which means this happened in the past and is still happening now. The same applies to sought/seek; decide whether you want to the sentence to describe the present or the past, and choose verb tenses accordingly.
Civilizations don’t travel, by the way; people do.
Also, you need a comma after workers.
The Land is an important location. People from many civilizations go there when they seek gold, aromatic resins, wild animals, workers, and more.
Still clunky, but now the “unimportant” stuff such as grammar and punctuation are correct.
