The missing delegation

The morning after the party's arrival to Red Larch‌ Garaele‌ finds them in the local Inn. She asks the party for their help, as she has been informed by The Harpers society‌ that a delegation that included a renowned shield dwarf historian named Bruldenthar, was transporting his collection of manuscripts to Waterdeep. The delegation traveled overland from Westbridge to Beliard‌ but hasn't been seen since then. She asks them to investigate and assist in the matter, as the Harpers don't want the sage or his books to fall into the wrong hands.
