- City alignments based on AD&D.

First, I want to say that Lord of the Rings and D&D cannot be compared because, although these two great universes intersect based on the fantasy setting and classifications of "good," "chaos," "order," and "evil," these two worlds cannot be evaluated or forced into the template of each other's laws and rules.
And second, the Krigan had a clan system, not a hive system.
