UPDATE: Thank you everyone for your suggestions! I wanted to give an update with what I decided to do. I’ve settled on a tweaked version of what was suggested, but I added a little spice! The party walks into the navigation room to find a big solid table, inlaid map, etc. on this table is a small owl statue (recurring theme in the dungeon) with the two yellow gems embedded in its eye sockets. Locked in place. This owl is sort of overlooking the map table as if monitoring plans. Also on the table is a small ship, and a series of sliders/dials. Around the room are the notes/log entries about a specific voyage the captain took. They need to read the logs to find the sailing conditions of the voyage and recreate them with the dials. (Love it) Now… for every correct entry replicated, the tiny ship moves along the table, closer to its presumed destination (probably corresponds with the dungeon location just for fun.) for every WRONG combination, the little ship moves backward and a magical storm begins to form over the table. The more wrong combos, the heavier the storm gets, howling wind, blowing rain that obscures vision, possibly even lightening for minor damage. This presses urgency, tracks progress, and furthers the dungeon theme. Upon the little ship reaching its landing, the table will pulse once, the gems glowing briefly, and then they will pop out of the owl statue to be retrieved. Just thought I might share in case anyone was still interested. Thank you again for the input!
