Okay Marivhon, you can't make it across the room (it's long) before the gate closes, but you can manage to reach the halberd in there and finagle the wheel... just a bit. It's enough to give some leverage, and with the combined help of burly Brogg, you can get the bars up... just a bit. It's enough to give you clearance, and you slip underneath and open the 'cullis the rest of the way.
The dwarf was stomped well and good, there's a lot of broken glass and blood, it's sort of an awful mess. However, you see his shield has remained intact- it's got a huge frothy mug of ale on it, the icon of the Dwarf God of course. Plus his mace is good too. Take it and move on, oh travellers.
From the depths, a cry and an explosion. Something is going on down there.
Are you resting? Healing? Or descending down deeper into the dark depths of this dank demon's demesne-cum-dungeon?
