The king and queen initiate the first attack. It was not something fancy or remarkable. Unlike the three hobgoblins, the king and queen have their own different weapons. For the king, he was wielding a scimitar in his dominant right hand whilst holding a bark shield in the other.
A scimitar is a short sword with a curved blade that broadens towards the point whereas the bark shield or gweagal shield is usually cut off from the bloodwood of mulga trees or from a bark of a red mangrove tree.
Based on the condition of the king's scimitar and bark shield, he must
have got it from somewhere or someone they killed.
"Monsters these days would use whatever means or form of the weapon just to survive. A bark shield suits his figure."
