On the fringes of the Outer Rim territories and famous as the one-time location of the Rebel Alliance, Hoth is a frigid world marred with fissures created from the tidal pull of Hoth’s three moons. Blanketed in a frozen ocean, massive oceanic currents beneath the southern hemisphere are the cause of constant seismic activities that result in a constantly shifting landscape of tunnels and caves.
Buried into the side of a fissure reaching hundreds of meters into the core of the planet is a network of tunnels leading into a cave. Its sole entrance is suspended within the wall of the fissure, requiring one to rappel down the dangerous crevasse and into the tunnels; one small miscalculation could send explorers descending the rest of the unmeasured height deep within the planet’s core.
Insulated under several hundred meters of ice in all directions, the cave is protected against the gale force winds and the intense snowstorms that sweep along the planet’s surface. As a result, the cave is warmer than most of Hoth’s unforgiving cold with melting icicles dangling precariously overhead. In turn, this allows for more life to grow in addition to being a promising habitat for the hulking Wampas that have been trapped this far below the surface. Beginning to thaw, it is obvious that this cave will eventually fall victim to seismic activity to disappear into the sheets of ice that surround it. Illuminating the cave’s interior with a dull blue glow, a luminous form of lichen has taken up residence among the bones of the creatures unfortunate enough to be trapped here.
Caution must be exercised if one is to navigate the slippery slopes of the cave as melted icicles drip onto the cavern’s floor surface. In one corner of the cave, the ocean water has accumulated to form a large pool, providing sustenance to the rare lumni-spice growing within the crystalline complex, never to see the blue-white sun.
Try to avoid repetition in your writing. Here you use "his own lightsaber" and "his own saber" in back to back sentences. You also have a "forceful swing" and "forcing him".
Second comma after "whether while training" is unnecessary considering the sentence structure and flow.
Tense dancing here, "has" instead of "had".
Overall, this is a well structured post. It had a lot of good set up and building of the conflict. Unfortunately, it didn't have quite as much conflict as we expect in a 2/2 match, leaving most of it to the following post.
