Welcome to Thrasja island, a small cluster of tropical islands (consisting of two major islands, and small dots of land, all of which is easily accessable) far from any other land, with a climate perfect for life. The forests on Thrasja are lush and tall, akin to the rainforests of Earth. There is a large lake near the top of the large island, between two peaks. Three large rivers go down the mountain, holding fresh water that feeds into the lake from an underground well. smaller creeks are common around the big rivers.
Meet the inhabitants of these islands below:
The Oco are primarily herbivorous, eating bark, leaves, fruit, tubers, and other vegetation, but are known to feed on dead animals and anything it can catch. They scale the trees of the island, using their large front limbs like ice picks. They are adept swimmers as well, being descendant from octopus-like creatures, as evident from their eight limbs and hard beak. Their sturdy exoskeleton keeps them mostly safe from falls and predation. Their long "tail" gives them balance while climbing, and a rudder while swimming. They are active at any time of day or night. Females will lay their soft-shelled eggs by the hundreds by the sea, or in rivers or lakes, wherever there is water. If any eggs find themselves out of water, they will not develop and "die" until water becomes available to them, and then the eggs will continue to develop. Oco are primarily solitary, but do not mind the company of other members of their species. Oco are mild-mannered and are generally only aggressive when hungry or looking for a mate.
Laz are plain lizard-like animals. They are capable of eating everything the Oco do (they are capable climbers and swimmers as well), but their main prey is the Hof. Laz must be active during the day, while the sun can warm their bodies, as they are cold blooded. At night, Laz are inclined to dig underground the beach, where the sand/soil is still warm from the sun's rays. They lay their clutch of 3-5 hard-shelled eggs in the hot sand. Laz are extremely aggressive and territorial.
Hof are small hoofed mammals, and are very similar to small rodents of Earth. They primarily eat vegetation and seeds, and produce many young quickly, as many as 8 young per pregnancy. Hof have keen senses, but have especially keen smell, which allows them to find the ripest fruit and keep out of the way of predators. They also produce milk on patches of their underside, letting their young lap it up. Hof make their homes in nooks and crannies, which can be under roots, inside a tree, or in small underground tunnels that the Hof or Laz dig. They are mostly active at night, when Laz are not a problem. Hof are somewhat solidary, but as there are so many of them across the islands, bumping into another of their kind is not uncommon or unwelcome. There is plenty of food and mates for everyone, so there is no need to be aggressive.
The trip I'm using is for events I will do in the future.
