Delben Larkspur

Delben Larkspur was a Kalrentai soldier serving at Greatwall Keep. He had formed an alliance with the Oni Targrek and a band of Neogi whom he had discovered in chambers below the castle. Acting as a go-between, at first he merely made some coin for turning a blind eye to the slave trade that was happening. Later, however, he lined his pockets with gold by becoming more active, selling information to Targrek about poorly defended caravans and visitors.
This came to an end when the Fire Wasps, commissioned by the Zhakastir of Gristamere to stop the slaving ring, slew Targrek and the Neogi and captured Delben. His final fate has yet to be decided, but it is likely in the hands of Captain Tolomos Greymantle, the military leader of Greatwall Keep.
