Vasco da Gama's Compass Needle

Origin
Vasco da Gama was a Portuguese explorer who reached India by sea, becoming the first European to connect Europe and Asia via maritime routes. He accomplished avoiding the highly guarded waters of the Mediterranean by taking a longer journey around the southern horn of Africa and to the Indian Ocean. While in the east, he was taught about the prevalence of monsoons and how to use their winds for easier travel. When Da Gama returned, the Portuguese hailed him as a hero for opening exclusive trade routes to Asia that cut out the middlemen and got them bounties of rare commodities. Da Gama is now considered one of the key figures in beginning the age of European imperialism.

Effects
When blown on, the needle gives impeccable directions to avoid obstacles. The northern tip will always locate the correct route to travel with the least amount of obstructions. Some journeys become long, winding paths while others are forced at times to go straight through perilous lands to avoid even worse encounters. The path behind the user will transform into a hazardous route, making travel for others extremely difficult.
