The Yellow Path

But what, you say, of our heroes who were swept up not by the purple or orange rays but by the yellow ray tending to the right?

They, being Spider-Man, Ant-Man, and the Vision, emerged on a wavy plain of undulating metal, like a once-molten continent cooled in the merciless void of space. Wisps of air cling to the lower surfaces, which fortunately is where the Earthmen have materialized.

To the left the plain of alloy abruptly stops, giving way to smooth grassy pastures dotted with house-sized patches of colorful clover. Bald men and women of exceptional beauty, marred only by the eye-hollows and worry-lines of desperate overwork, toil mechanically pulling weeds and planting writhing purple worm-like crops.

To the right, the plain drops sharply to jagged burnt-gray towers jutting like broken stumps from a cracked, seared street plan out of a madman's delirium. Aliens with multiple slash-like mouths and a huge bloom of tentacular hair, clad in stinking rags, haul on a red iron chain to pull down another of their war-ravaged tenements under the literal lash of five-chinned, pointed-eared, pea-green Skrulls!

Behind, the metallic meadow is abruptly overlapped by a towering cliff of purple glass, into which six-limbed, red-chitinned insect people, also in rags, labor to chip tunnels deep into the fragile face to extract pulsating black baubles, which they leave on the ground to be picked up by another Skrull! As the Rainbow Wind dies, a section of the cliff forms a crack, from some unwise blow of a hidden miner, and half the cliffside crazes into long, pointed fragments of broken glass, about to slide in a thunderfall of crystal upon the insect miners below!

And before the heroes, directly to their front as they emerge, is an insolent black fist of a fortress, crenelated with battlements like clenched knuckles, topped by spiky black death rays, overflown by multi-winged air-kites bristling with needle spines, and fashioned in the shape of a huge, brooding, sunken-eyed face -- the face of Thanos, the mad Titan and suitor of Death!

This, then, is MORDEMOND -- Thanos' capital world, assembled from the shards of shattered planets!

Or so the Vision recalls from reading the Avengers archives.
