Nostalrius Begins - Quality wow vanilla realm (1.12)

I arrived in Silithus and completed the quest Armaments of War thinking that it was just another quest in my log that I forgot to hand in, and then sold the items to a vendor and they've disappeared from my buyback menu.

I Believe the items sold for about 8g collectively and i'm assuming I made about 2.5g from the quest itself. I will gladly forfeit all of it if it means keeping my character!

my character is Kicko - level 60 orc shaman
