This funny , cuz, I've just crawled out from under a rock and finally bought Morrowind ... ( should have paid the extra 20 bucks and bought GOTY... but hey, it was $8.50 ...

)
anyway, I'm working on building up my scripting and world-building skills ( I had practiced with Terragen throughout Morrowind's Development time ... and then lost interest) ... so that I can apply here to help out in the mod .... well.. the funny part is that I want to practice by making a Umbar mod ...
Umbar should be a province, with a major port-city/capital with the same name ...
Architecturally, it should have a central "old fort" region whose architecture should be OLD Numenorean ... and then, in wave our from there, Exiled architecture that has Harad influences ... both light and heavy in different areas ... With sections of the province strictly given to one or another culture ... thuse having towns/boroughs within the major complex of Umbar ... Remember that the old Numenoreans ... mostly what have been called Black Numenoreans ... would have been extremely proud and Haughty and would have build areas just for themselves .. walled off from the rabble. .... something that the Later corsairs would have continued to do, since the civil war that exiled them to Umbar was over blood-purity ...
What would be cool is ... what ever is done in Pelargir, the Devs should try to mirror in Umbar ... make Umbar seem like the Yang to Pelargir's Yin ...

.... the Agent Smith to Gondor's Neo ...
I missed the Jungle reference... and there is nothing in Tolkien's writings that would support or deny that .... there isn't much of anything, actually ... BUT ... you do get a sence of Tolkien mirroring Mediteranean and Arabic "pirates" and culture clashes when refering to Umbar ... You would have more of the Hot Desert/ with Semi-Arid Forest, instead of Jungle ... but then, as always, I could be wrong.
