Omega

As Miranda so elegantly puts it, Omega is the "pisshole of the galaxy," and it's no wonder that she thinks so.

Batarian Bartender

Reward: XP

At the main bar of Afterlife's lower levels, choose to order a drink. Although Shepard may not be able to hold his alcohol, one drink shouldn't send a full-grown man to a slump like that. It looks like he's been poisoned. A random stranger who witnessed your ordeal informs you of the Batarian's natural dislike of humans and his bad habit of trying to poison them (and often succeeding). You're the first person who's ever lived through this sinister plot, so you can now exact revenge without raising his internal alarms. Return now to the unsuspecting bartender who idly passes you another drink. Upon doing so, you have two choices: loudly berate him so the other patrons can hear or force him to drink his own poison. Either outcome delivers a well-deserved--albeit gruesome--death to this vile bartender. That concludes this very short and interesting side quest.

Deliver Datapad

Reward: Data on a N7 mission

During Archangel's recruitment process, you will run across a data pad on a table sitting behind Jaroth of the Eclipse mercs. You simply have to take this data pad to Aria, who is grateful for this message.

Missing Assistant

Reward: XP

After agreeing to help Mordin, he mentions that his assistant is somewhere out there and has failed to establish communication with him. Worried for his safety, Mordin tells you to seek out Daniel to make sure he's all right. After leaving the clinic, follow the somewhat linear path toward the Environmental Control. If you go through the left door in the hallway, you encounter Daniel, who's in a bit of a bind with some hostile-looking Batarians. Apparently, the Batarians accuse Daniel of spreading the plague and are just about to do him in until your arrival interrupts them.

Now you can either settle this matter peacefully and let Daniel return to Mordin ultimately unharmed, or allow yourself to be equally as quick-tempered and endanger his life. We chose the Paragon route in this particular instance, and as a result, Daniel fled the scene safely and generously left behind a Medi-Gel.

Packages For Ish

Reward: Credits and XP

Before you can undertake this quick and easy assignment, you must first successfully recruit both Archangel and the Professor. Only then will this enterprising Salarian request your help in helping him bring two shipments back to him on Omega. Of course, you will be rewarded for your time. These shipments are in the form of datapads. The first is at the Citadel located atop some crates outside Saronis Applications. The second can be found on Illium, visited via the Crescent Nebula. Head to the Eternity Bar in the northeast corner of the map and grab the datapad from within one of the vacant seats. Collect the two datapads and return to the Salarian merchant for the dough he promised. The conversation is a good chance for Renegade points if that's your thing.

Struggling Quarian

Reward: XP

Kenn, a young Quarian who's become stranded on Omega, runs a small salvage shop called Kenn Salvage and barely ekes out a living with indubious misery. The main reason for his anguish is Harrot, an elcor who owns a shop on the main floor. Harrot stamps out any hope of Kenn making enough money to catch a ride off this by forcing Kenn to drive up his prices in excess so that Harrot's own business booms. Help this poor bloke out by either generously offering to pay 1,000 credits for his ticket off Omega or having a word with Harrot about his crummy business tactics. If you go with the latter, visit the Elcor on the main floor at his establishment and bring up the deal with Kenn.

Whether you do it through fear-inducing intimidation or by appealing to his sense of reason, the Elcor, catching wind of Shepard's flaring disapproval, is easily swayed and agrees to loosen his dominion over the defenseless Quarian. Return to Kenn with the great news and, if you still have the FBA Couplings quest, buy the couplings from his shop.

The Patriarch

Rewards: XP, Data on a N7 mission

This mission becomes available only after you conclude your business with either the Professor or the Archangel. One of Aria's bodyguards at the base of stairs, Grizz, imparts a request from Aria concerning an old "acquaintance" of hers known as the Patriarch. Word has it now that the some of the local thugs want Patriarch dead, but Aria wants him protected for both his and her sake. See if you can persuade the old-timer to make himself scarce for a while until things blow over. If you've been snooping around the Afterlife bar, you should already be acquainted with the weathered krogan. If not, he can be found in one of the rooms on the lower levels of the bar, preaching to anyone willing to lend an ear.

When you approach the Patriarch, he is unsurprised by the developing circumstances and scoffs at Aria for her supposed concern for his safety. You can help him eradicate the Blood Pack threat, or just tell him to go into hiding. Aria would not be too pleased with the former option, but once the matter has been dealt with return to Grizz to complete this assignment.
