Valdryx's Spectral Deckhands

Chanting an incantation that calls on the spirits of seamen lost to the depths, you summon a crew of ghostly sailors that make your ship ready for you. When you cast this spell, the crew manifests on a nearby ship you choose within 200 feet, or around you if no ship is nearby. The crew cannot speak, but they understand and carry out commands given to them by the caster to the best of their abilities. The crew cannot interact with anything but physical objects pertaining to their duties; irrelevant objects (such as a projectile) and people that attempt to interact with them will simply pass through. The crew will begin to audibly sing together in unison while they work and can be heard from up to 100 feet away. If they are given no orders, they will simply remain where they were summoned, but continue to sing for the duration. The crew can perform the following duties as directed by the caster:

• Tie any nearby cords (rope, thread, fiber, twine, etc) into a steadfast knot, or untie them.
• Light or extinguish any nearby light sources. (lanterns, torches, candles, etc)
• Prepare any nearby sails to get ready for sailing, or stow them away and prepare a ship to be docked.
• Transfer any goods in an assembly line to a desired location, such as crates of food, barrels of ale or water, etc. 

In addition, whenever you perform this spell, you become aware of extreme weather phenomena within a 25 mile radius centered on you. The knowledge comes to your ears as an ominous wind blows and ghostly whispers warn you of potential threats from that direction within the next 12 hours.
