Your faction standing with Merchants of Qeynos (10+) got better.
Your faction standing with Circle Of Unseen Hands (-30) got worse.
Your faction standing with Antonius Bayle (10+) got better.
Your faction standing with Coalition of Tradefolk (10+) got better.
Your faction standing with Guards of Qeynos (10+) got better.
It is for sure one of these. I've taken two iksars from scowls to amiable+ simply by doing this quest. Probably Coalition of Tradefolk then.
