The characters now probably know that there are things that live below. Perhaps they’ll want to try and explore further; you may decide that there are more intelligent creatures of the underground who occasionally travel above ground. Or perhaps there is an older city beneath the city of Crosspoint, and something must be retrieved.
Or, the glimpse of the underground can be temporarily forgotten. Depending on how the characters resolve the ripper murders, they may either be heroes, or have to leave town quickly. Their uncle may decide to help them with, for example, a recommendation as caravan guards. Or he might send them after a caravan lost many years ago, that he thinks might still be intact somewhere across the mountains and in the deep forest.
The short swords of the Oruat are well-made, with an interesting snake (or worm) design on the hilt. The leather of the hilt is an unknown animal (an underground creature). The swords are worth ten shillings (each, if there are more than one).
