The Helix Barrow Mounds are located a half-day march from Helix. This is the burial site of many noble families from centuries ago that were worried about being robbed, so they hid their burial sites far from Waterdeep. Over the years, the lands around the burial site turned into a swamp and many of the grave entrances became uncovered.

The villagers of Helix, on more than one occasion, have seen the dead rising from the burial mounds and walk the swamps.
