Yeah some are complete duds, others are a series of quests with the last one having a decent reward. I enjoy doing them regardless of the rewards just to see what’s in there. Not like it’s going to make a major difference to my game to give a few goods here and there
On a more serious note - this quest does not have a random reward. It's a hidden reward and for future reference, you can search for this quest on the FoE Wiki and see what the hidden reward is and decide whether or not the quest is worth completing.
