Bars of frustration

Firing arrow after arrow at the Hobgoblin slavers from behind the safety of the portcullis, Vogir shouts for the others to advance.
The Hobgoblins are clever though and (dragging Daelagor behind them) flee from Vogir's line of fire towards a side room.
Running up as quickly as they're able, Egil and Bayern struggle with the metal portcullis until Vogir drops his bow to aid them.
Slowly the bars bend apart until even the Dwarf can slip through.
It’s too late however.
The Hobgoblins have made it to the next chamber.
