OH BOY OH BOY, MORe questions :^))))))
According to my Totally Accurate Geography Simulator (T.A.G.S.), it is sort of situated here:
It is situated in the great sandy desert of Shifting Expanse that we call Teshert, in the delta of the medium-sized but sluggish river Nekhir. Yes, Teshert means desert and Nekhir means river; Desert Desert and River River.
Due to the proximity to the equator, the conventional seasons are practically non-existent; there are only the dry season and the rain season. The climate is hot and dry but due to the ocean, there is enough humidity, even if it's low, to keep the night-time temperature steady and not dwindling to low temperatures. The abundant rain season lasts only around a week or two, refilling the pools that accumulate in the sand in some areas of the oasis (look up Marahenses National Park).
The delta is seemingly very similar to the Nile delta, with lots of shrubbery, grass and trees near the muddy riverbank. It is mainly a very sandy land with fertile soil only around the riverbank and near the lake, the coast has both rocky and sandy beaches and rocky cliffs. The delta has solid ground even though sand covers most surfaces, but there are large sand dunes that are scattered throughout the oasis, mainly on the border. The oasis itself isn't very big and neither is the delta, but it is efficient.
The flora mainly consists of short grasses and flowers (cornflowers, opium poppy, jasmine, irises), even a type of bamboo, many reeds like papyrus or cattail, other water plants like all sorts of waterlilies and duckweed, hardy and resistant plants and shrubbery (like lavander, sage, rushes, phlomis, Samwa, roses, ivy), then many acacia trees, figs, tamarisks, Bay laurel trees, palms, cypresses, stone pines, cedar, Joshua trees, olives, and many cultivars like apples, pears, pomegranates, plantain, watermelons, melons, cucumbers, aliums, beans, lettuce, cabbages, carrots, desert grape vine, mulberry, etc. All in all, very unique and interesting flora.
Many types of arthropods are present, arachnids such as scorpions, solifugae and spiders are a common occurrence, then insects like flies, butterflies, fireflies, beetles like scarabs and giant desert beetles, mantises, locusts, grasshoppers, leafhoppers, cicadas, moths, dragonflies, termites, bees, diving beetles.
Harvest Hardshells and Plantation Pinchers are very widespread crustacean species, but there are also other rock crabs, ghost crabs, hermit crabs, even coconut crabs, king crabs, lobsters, crayfish, etc.
I'm way too lazy to rewrite this again so I'll list the most commonly-known vertebrates: bass, Nekhir perch, tilapia, catfish, carp, mullet, lungfish, sardines, anchovies, trevally, seabreams, arapaima, gars, Arowanas, all sorts of toads, frogs and treefrogs, monitor lizards, geckos, wall lizards, iguanas, cobras, boas, box turtles, crocodiles, toridae, herons, egrets, flamingos, ibises, rock doves, spoonbills, swallows, cormorants, all sorts of waterfowl, vultures, cranes, eagles, hawks, kites, falcons, desert owls, parrots, hummingbirds (and chickens are all over the place), cheetahs, caracals, lions, leopards, chimeras, Manticores, Mau cats, Pharaoh hounds, spotted and striped hyenas, desert wolves, desert horses (kek ses), donkeys, pigs, boards, pohips, sheep, goats, antelopes, ibexes, oryxes, camels, ETC
