The first group of tasks that the guild looked into was all in the Frozen North. There were a number of quests to accomplish. The powerful and mysterious scourge of the Phaerim has returned. Possibly to unleash powerful magics in an attempt to destroy the world all over again, or possibly just a few random monsters roaming the waste lands. The wayfarers were no match for these powerful creatures, so this was purely a scouting mission.
There was also a matter of assisting the dwarves of Mithril Hall and their King, Bruenor Battlehammer with a nearby Drow city. Since the Dwarves did not have the means to go to war with the drow, King Battlehammer just wished that a treaty be made and an outside force was the best bet.
Also scourging the Frozen North were frost worms. These hideous creatures were destroying caravans, settlers, and even small contingents of troops with reckless abandon.
Finally there was the matter of the city of shade and their purpose for returning.
The first task the guild undertook was the Dwarves and the Drow. They successfully brokered the treaty, but the biggest success was a group of dragon eggs, that would have been handed over to the Drow if the group had not had the foresight to write the treaty correctly. In the end the guild wound up having trade agreements with both the Dwarves and the Drow.
The frost worms were merely overlooked. By purchasing wands of fireball, and better weapons and armor for their caravan guards, they hope to avoid having to worry about them for sometime. That any frost worm looking to devour a few dozen people in a caravan would quickly rething their actions when they got hit by a pair of fireballs.
The city of shade and the phaerim were both taken care of by gaining access to the city of shade and talking to some of the more friendly shades there. The most important bit of information was that the phaerim had indeed returned in force.
After all this, they returned back to the main guild base in Waterdeep to rest a little, resupply, and set back out on their next set of missions.
