Wacega, Oonar in the native tongue, is an ugly world from orbit. Two great continents and countless archipelagos are a mottled red and orange, with deep blue oceans creating a burning contrast between land and sea.
Wacega's gravity is significantly higher than Earth's, almost twice as strong. Any human visitors would find themselves rather uncomfortable in such conditions, as if wearing clothes made of lead. Wacega's parent star is a K-class orange dwarf, casting a warm orange light over the planet's surface. Corresponding neatly with this, Wacega's flora is autumnal in colouration, the ground blanketed in springy, crimson "spongeweed", a vague parallel to Earth's grasses. The barnacle yam is the largest floral lifeform on the bloodplains, a large biome that border's the northern continent's inner desert. The tallest can rival Earth's palm trees in height, nearing 60 metres tall, most of which is the almost metallic stem. The thicker atmosphere of the planet supports a richer aerial ecosystem than Earth, including numerous herbivorous creatures. The barnacle yam's counter to this lies in its rigid stem, into which the photosynthesizing organ can retreat in the event of a threat. The lower part of the yam resembles some kind of corpulent, veiny worm. This sturdy base is how its height can be attained, the inches-thick, leathery shell can bend accordingly to the wind, and is near impenetrable to most herbivores.
While bizarre through the eyes of a human, to the denizens of Wacega, both thinking and not, the barnacle yam is just another tree on an otherwise bland savannah.
