After rescuing a group of people captured by slavers in the stony barrens east of Tyr, the party returned to the City-State to bring them to safety. The group, then, decided they needed to finish the first job they accepted from House Ghadir of Tyr to deliver a small cargo to their representatives in Urik and went their way to the Caravan Gate. That is when they realized they were being followed by about eight bandits from the Toothcutter's gang.
The group was not worried with this and just kept walking to the gate. That's was their mistake. The gang knew the streets very well and surrounded the party. Their leader, a mul, said the adventurers were putting their noses where they shouldn't and attacked. Since the characters were surrounded the fight was pretty rough, and the bard/shaman was almost killed and left behind. The group managed to kill the gang leader and a good number of thugs, but more were coming and they were already seriously wounded.
