Hello there Landale. Welcome to the Oddworld Forums. I'm not one to introducing myself, but this seems like the perfect place to do so. Perhaps you will appreciate the title peope have thrust upon me: The Oddworld Encyclopaedia (or Dictionary. It varies).
Firstly, the Octigi Family is a biological set of creatures of which the Glukkons are a member. So far, we know of three other members of the family. Looking at the below picture, you will see that they are named as 'Gloctigi', '0.1' and '0.2'.
0.1 is interresting because it gives a clue to the relationship, biologically speaking, between the Glukkons and the Sligs...closer than we'd imagine, methinks.
0.2 is rumoured to be the species that forms the Oddworld Mafia.
Now, the Chroniclers are the accountants, lawyers, stock-brokers and thieves of Oddworld. They run the financial stuff, and they're after Lady margaret who owes them a lot of money. You'll find out why later.
Khanzumerz are the most important species on Oddworld, as far as the profit-greedy Glukkons, Vykkers and Chroniclers are concerned. They buy all the consumer goods and all. No one knows where they get all that Moolah from, though. No picture, I'm afraid.
Lady Margaret is in trouble, not only because her lungs are giving in, but her most profitable child, Molluck, has been reported missing since the closure of RutureFarms. She's very angry with him, even though he's her favourite kiddie, because now she has to pay the Chroniclers all the money for the factory, the products, the GSP-type stuff - all the stuff you really don't want to know about.
Which was where Lulu came in. He was the purchase RuptureFarms and find Molluck etc. etc. OWI changed story blah blah, who knows what'll happen know.
