Any Sugestions?
First off Gandrel, yes Kreen are a nomadic people but they still partake in trade amongst the sleepers. In Raam there is a standing population of Thri-Kreen, they are called the Raam-tek and number between hundreds to a thousand.
By saying "Special Crystal", you mean Dsal or "Reverent Crystal", then yes they do normally make their weaponry out of it if they have the proper craft skill - but metal is metal. Even still the Dsal is not made from nothingness, there are components other than the venomous saliva of the Kreen - Zik-thok being the most important (Trans: "Changes Earth" (the herb that allows the creation of Dasl)) that may be purchased in various cities, plus there is the choice of the last main ingredient: sand. While in a hurry any old sand will do, but Chatkcha alone have a more personal significance, something of a cultural icon never to be seen in the hands of a sleeper-meat-beast so the choice of sand may become important to the individual, say the sand from some great battle location – like the sands of an arena.
A couple of other reasons to enter into a city, a lone Thri-Kreen are just that, alone. Kreen have their clutch mentality that forces them to want to be part of larger groups, even if that group is made-up of sleepers (the kreen term for humanoids) also Thri-Kreen will sell their services as guards, warriors or gladiators. Lastly, what kind of Thri-Kreen does your player have, elf-addicted yet – there are always tasty elves in cities!
The sugested motivation of my DM, looking for iron, sounded very dumb.
Oh yeah, another question: the natural tendency of a thri kreen is lawnful or neutral?
Lawful, Thri-Kreen have ordered minds with a strong belief of family bonds.
The requirements of a clutch transcend alignment. Thri-kreen might be good or evil, lawful or chaotic, but the thri-kreen still behaves the same way toward clutch and clutchmates. Regardless of the thri-kreen’s true alignment, behavior toward clutch and clutchmates is essentially lawful good. This is one of the reasons why other races consider thri-kreen unpredictable, whether they are truly chaotic or not; a thri-kreen that behaves one way with clutchmates might behave in a strikingly different manner with others.
You really should try and find a copy of the "Thri-Kreen of Athas" game supplement.
EDIT:
Oh and to answer your second post, Thri-Kreen make real good rangers. As for PrC's check out the two "Prestige Classes" PDF's from Athas.com. There are a few Kreen-based ones in them.
I've been a fan of the Kreen sense their first appearance in Fiend Folio back in the mid-eighties, well before Dark-Sun. They’re what initially drew me to the setting.
Correction. Kreen appeared in the 1st edition Monster Manual II, not the Fiend Folio. ;)
1. Why not?
2. Its there.

I like simple explainations. Reason for Kreen to go to city.
1. Why not?
2. Its there.

And NOBODY is going to tell a Thri-Kreen where he can and cannot go in Zardnaar's game.
