hello there!
this is something i`ve been waiting for. a Lotr-mod.
here is a link to civ3 forum, a thread i have been following for nearly a year (or 2). it`s a lotr mod for civ3. i believe that you will find lots of usefull information of units and nations from there. believe me when i tell you, that those guys have done lots of research.

i hope the link works.
btw, can you script item so that it would be lost in the province where carrier were slain? and then some unfortunate gobyer would find it again? like the time that isildur (was it isildur?) fell i the river, and years after smeagul found the ring.

edit: i took a second look to dates.. is this mod still active?
