Thank you for the quick response to my previous comment. I believe its the entire gatherer achievement chain now. I just got the next one in the sequence and it still has not yielded a reward. Thank you for your time :).
I just got gatherer 2 but did not in fact get the imperials associated with said achievement. I am also pretty positive I did not get imperials for a previous Gatherer achievement as well. Thank you for your time :)
