The Compass is a navigational device that displays a stable reading pointing at roughly "11 o'clock," which is unusual compared to its prior erratic behavior. It can indicate local sources of attraction, as demonstrated when it locked onto a giant creature.
While exploring underground tunnels, the Compass maintained its stable reading as the party advanced stealthily. It pointed directly at the giant guardian creature, indicating a local locus of attraction. The group noted that the creature's source could override the Compass's direction, but it was overshadowed by a larger distant source when farther away.
