===Noble Phantasm===
Sinfjötli's Noble Phantasm is the underworld ship Fjord Drakkar. The great god Odin ferried the corpse of his blood descendant Sinfjötli through the fjords on his ship. This ship is an underworld ship meant to traverse between the realms of the dead and the living, so it can be used as a form of Self-Destructive Noble Phantasm that takes his prey's souls away from the present world along with himself.
Fjord Drakkar takes the appearance of a Viking ship. Its speed is regulated by a sail of light on its cross-shaped mast, and the rows of shields on the flanks of the ship can serve as magical energy thrusters. When not using the ship, its mast can be used as a pike.
In Fate:Lost Einherjar, he sails it alongside Percival, thus utilizing this as a powerful mobile weapon that makes best use its mobility and stealth capabilities while using Percival as the ship's "main cannon". His Master forbids him from unleashing the Noble Phantasm's True Name as that's how he can use the Self-Destructive Noble Phantasm form.
