Four adventurers from the Sword Coast found themselves in the town of Greenest which sits astride the trade route from Iriabor to Amn. Each had their own reasons for coming here and were all staying in the single inn in town.
Shortly after dark they heard screams, yells, roars, and the crackle of lightning. Running outside they found the town under attack by raiders and kobolds and a large blue dragon soaring overhead occasionally swooping down to blast it’s lightning breath. A family ran across the street ahead pursued by kobolds. They charged into the fray, and saved the family though two of them were badly injured by the little reptilian beasts.
The mother of the family was Linan Swift and she told them they were trying to make the keep in the center of town. The adventurers set off with them for the safety of the keep.
They ran into two more groups of raiders amidst the chaos of the attack. Both times they charged into battle, both times they paid in blood. Badly injured and nearly depleted of spells they made it into the keep with several other refugees just as the militia were sealing the gate.
They met Tarbaw Nighthill, Governor of Greenest and his Castellan, Escobert the Red. Nighthill said the town was fortunate to have adventurers in town and asked if they would help. He pointed out a large group of raiders heading for the church and said the reports were that there were a large number of townsfolk barricaded in the church of Chauntea and that Father Eadyan Falconmoon was the best healer in town.
The adventurers agreed to rescue the people in the church and bring them back to the keep. Castellan Escobert said they could try the old tunnel under the keep that ran to the stream on the south side of town. It was there so the defenders could get water in case of a seige, but had gone unused for decades. He showed them where the old tunnel entrance was and gave them a key to the grate that covered the end.
