You name a destination and conjure a Gargantuan force in the form of a spectral whale, which appears in a body of water within range and lasts until the spell ends. If there isn’t enough room for the whale to manifest, the spell fails. When it is conjured, the whale immediately devours you and up to 5 willing creatures of your choice within 10 feet of you, and then begins traveling toward the named destination, which must border a river, ocean, or other body of water, or be underwater. If the destination and your starting body of water are not connected by at least one water route, the spell fails.   The whale has a swimming speed of 300 feet, and can move 30 miles in an hour (240 miles in 8 hours). It travels at a depth of 30 feet in bodies of water that can accommodate it, or otherwise along the surface. Upon reaching your final destination, the whale disgorges you and all other passengers on the shoreline nearest the destination, and the spell ends. If the whale does not reach the destination by the time the spell ends, it discharges all creatures inside it on the nearest piece of solid ground.   The interior of the whale is warm, comfortable, and relatively dry, with enough air to sustain all passengers for the duration of the spell. Nothing—not physical objects, energy, or other spell effects—can enter or exit the whale. The whale is immune to all damage, and a creature or object inside can’t be damaged by attacks or effects originating from outside, nor can a creature inside the whale damage anything outside it.   A disintegrate spell targeting the whale destroys it without harming anything inside it.
