Imagine a group of dwarven warriors, battle hardened professional specialists. They get ordered by the Lords of the Deep to retrieve an artifact which is the key to repair an old Digging Machine, which has gone haywire and threatens to destroy your home, the Mine City. After gathering intel about the location and stocking on equipment, they travel to the site of an abandoned ruin. It is an old castle, a remnant of the Old Kingdom of man from before the cataclysmic winter. The group’s scout takes a look at the surrounding area and finds out that a group of kobolds have established a lair inside the old halls. Those critters are not much of  a threat, so the warriors decide to take a head on approach. They charge head on into the entrance hall and surprise a group of scattered kobold scavengers. While the warrior’s fighter draws the attention on him, their wizard prepares a spell to deal quickly with the whole group. Suddenly a rumbling sound. A door leading deeper into the castle bursts into splinters, only to reveal a huge combat drake. It charges the fighter and pins him to the ground. They now have to think fast and come up with a new tactic. The scout scales a half decayed balcony to stay out of melee combat and starts peppering the reptilian beast with arrows. The wizard pushes the beast off their fighter with a thunder wave spell. Now it is up to the cleric to patch the injured companion back up. Only with combined efforts they will survive this.
