((That spleen’s still up for grabs. Though I’ll assume whoever gets it has it immediately in their inventory via retconning.))
That evening, you feast on a meal of fish and potatoes, the dwarven cook proving more than adept at his art. After toasting Ryxa, the captain lets you eat, before proclaiming that you are within a few days travel of Bastion.
Sure enough, two nights later, you are woken from your slumber by a call. Stumbling up to the deck, the sight of land greets you. Across the horizon stretches a solid band of rock, mountains towering above it in the distance. And in that band, directly in your path, and growing larger by the second, a crack in the cliff face, it’s edges illuminated by the red light of the rising sun.
An hour later, the crew, all now wide awake and ready, stand on deck, and the ship slips inside the crevasse, with space for just two more on either side. The light fades, and torches are hastily lit by silent dwarves, glancing nervously at the canyon walls at the slightest noise. The reason why is soon revealed as you pass by a cave mouth, and from the entrance pour forth horrid creatures, silhouettes of no discernable pattern or species. At once the sailors rush to the rails, weaponry in hand, but the creatures do not respond, instead swarming with you, along the walls, and towards Bastion. As you draw closer you find another such hole into the rock, and another, until the walls around you are hidden behind waves of shadows, a tide of darkness.
And then the walls fall away to your sides. The river ends abruptly in an artificial lake, embedded in a large open square, ending with the crevasse in a solid wall, a giant pair of double doors set in its base. Bastion. The shadows drop from the walls into this square, covering the ground, and converging on a single figure standing in the shadow cast by the fortress-city. With a roar he swings his warhammer, a single mass of bone, and the silhouettes fall to nothing before it. in their place rises the earth itself, elementals of mud and stone rising to defend their master. Then, with a resounding cry, the ship pulls in to shore and the dwarves leap into the fray, none staying behind.
