Droga mobs are lvl 35-45, you can find more info on the Wiki:
http://wiki.project1999.org/index.php/Temple_of_Droga.
Chief Rokgus' (~2% of the zone) was a highly desirable camp when Kunark first opened, and you might still find people there, but most of the rest of the zone is likely to be wide open for you.
Have fun and watch out for casters!
