Dewadems can be used to fertilise plants, invested into building new booths for new residents as they join the party, or used to synthesise new items at the hero's house, be it consumables or pieces of equipment. The purpose of Bloom booths, which the hero has to keep supplied with the types of resources they need to craft their wares, is simply to attract Noots, earning the game's currency: Dewadems.

Last, but by no means least, there are three races of desert dwellers that can also be turned into permanent residents of the oasis - Drauks, Serkahs, and Lagoras - who are all mostly characters used in the action RPG sequences and do not run booths at all. Other seedlings are playable characters that join Tethu in the action RPG exploring sequences. Booths are, in turn, run exclusively by other seedlings, each being unique and selling a different type of item. These are non-specific, silent, non-playable characters devoid of any personality. There are several races that come wandering in, the main one being Noots who are entirely neutral creatures that do nothing but spend money in booths. As more characters come to settle, the latter can be levelled up and expanded as a result, allowing for more booths to be opened. Some of them will just wander into the oasis on their own, being only visitors at this point, until Tethu speaks to them or does something for them that will prompt them to stay there. The primary goal, in the initial stages, is to gather new residents. It is comprised of the water spring itself where Esna dwells, the hero's hut right beside it, a small garden where fruit and other seeds can eventually be grown, a small market-like sand path where Bloom Booths can be grown, which act like shops tended to by oasis residents, and an entrance plaza where other miscellaneous booths are progressively added to streamline certain functionalities of the game itself. Managing the oasis is at the centre of the experience. Being a seedling that received training from his brother to become an oasis chief himself one day, Esna and Tethu team up to create their own, last oasis, hoping to grow it so big that the forces of Chaos could never destroy it like the others and, hopefully, being so large that it could destroy Chaos itself once and for all. He soon finds a lonely water spirit, Esna, who sensed the other remaining water spirit disappearing with Tethu's oasis. This is what soon happens to Tethu's oasis, his brother seemingly sacrificing himself to spirit him away to save him from the powerful Chaos monster that took over their oasis. Such spirits, however, have become increasingly rare because the evil power behind the desertification of this world, Chaos, relentlessly attacks and invades the oases with Chaos plants and monsters, making them disappear altogether.

His brother is an oasis chief, meaning he runs the place and is the only one to be able to communicate with the water spirit that keeps the oasis alive. He lives with his brother in an oasis in the desert, in a world that is covered with nothing but sand, where oases are the last havens where life can truly thrive. Tethu (or Tethi, if choosing a female avatar) is a seedling, a child of the Great Tree.
