Adventurers Needed to help activate a portal

The adventuring party encountered several poisonous plant monsters, boars, and wolves from which they handled only suffering minor blows. When they got to the entrance they saved a different party of adventurers and had them delay anyone else trying to come clear the dungeon. Then they defeated a giant boar defending the entrance to the dungeon. Before they entered they found a magical rock. In the dungeon they found many traps and a small amount of silver in chests. After navigating the dungeon they fought a long and grueling fight against a tall oversized weapon wielding monster. After defeating the boss they found a magical cloak and quickly activated the portal finishing the mission. Each adventurer got paid 9000 silver by the employer because they pulled shenanigans after the portal opened.
