Cervucean is a Water-type creo that can summon warm rain whenever it wants.
People in cold climates worked out quickly that fertile ground and fresh water appear wherever a Cervucean walks. Cervucean themselves neither seek out human company nor run from it, unless they feel threatened.
Biology
Several shades of blue combine in Cervucean's striking coat. Its antlers alone go from deep indigo at the base through periwinkle and teal to a pale blue where they taper to an icicle tip. A full-grown Cervucean stands 2.3 m and weighs 195 kg, which makes it a hard animal to threaten.
Oddly enough, Cervucean cannot eat the plants that spring up from the warm rain it summons. It lives instead on water plants found along riverbanks, lake edges, and in the shallows, including nutrient-rich algae and kelp.
Flowers and greenery bloom wherever Cervucean walks, which is especially welcome in the cold places it lives. Out on tundra where the permafrost almost never thaws, one Cervucean can create an oasis of growth, at least for a while. When it moves on, the site returns to what it was, so the balance of the ecosystem is never permanently upset.
Those oases benefit the other plant-eating animals, and indirectly the predators that wait nearby hoping to pick off the weak. No predator dares attack the oasis itself, for fear of Cervucean's icicle-sharp antlers.
Cervucean are at home around water in every form: snow, ice, rivers, lakes, and oceans. They swim and dive. On ice they either skate nimbly or pick their way across, surefooted either way. They can even cross stretches of open sea by leaping from one ice floe to the next. Cervucean spread themselves out across a region and rarely travel in large numbers, so that neither their feeding nor their weather-bending puts too much strain on one place.
