By purchasing a lamp you become a genie's master. As most of the vendors lamps are new genies (freshly created by Al-Majeed). Most Genies will have three stages. The Lamp will be in every single stage as it is always important to them, and their gateway into our world.
Wisp - The Genie is nothing more than a small elemental "wisp" coming from their lamp. Some of the unique colorings may show up in this stage but they lack almost any definition.
Youngling New! Click Here - The Genie is more humanoid, and their specific gender has appeared and only have created sparse clothing for themselves. They appear as something of a pre-teen.
Full-Fledged - The Genie has reached their full potential, their physical appearance is very developed as are their clothes and hair and they even will probably carry a weapon they associate with themselves.
Noble - This is the highest class of Genie below the Lords, they have direct say in their world and demand the respect of lesser genies. They are larger and more elemental looking than normal genies.
There are (currently) four types of Genies.
Djinn are known as the most regal of genies. They deem themselves above many of the other breeds of genie, (perhaps due to Al-Majeed himself being a Djinn) much to the annoyance of the other Genie. They have the ability to project themselves as noble and as powerful as they truly are. Unfortunately for the Djinn they are very flighty and will often change topics or loose interest with nary a notice. This has caused them to be taken less seriously than they feel they deserve by even their Masters. Djinn are the most famous Genies of legend and often do their best to come off as intimidating as possible, certain darker Djinn seem to feed and live for the fear of their masters. While other Djinn seem to feed more off of pride, respect, and appreciation .
Efreeti are spiteful and capricious, although they can carry a very noble air they are notoriously known for having hot, and easy to set off tempers. Being both powerful and destructive, they more often demand respect than try to earn it. Efreeti rarely have tolerance for anyone they deem "lesser" and are often bitter servants. They have been known to try to corrupt their own masters and lead them down a path of eventual destruction. A wish from a Efreeti is often the most dangerous kind. This has caused them to be attributed to many stories of demons who will grant power for a soul. The first Efreeti (Ibilis, brother to Al-Majeed) was rumored to have actually collected souls.
The Dao are a slow, stubborn, and contemplative breed. They are known for stoic personalities and dedication to a task, they can work one thing, for longer than most genies would care for. They often come into conflict with their Djinn brothers over just this. But because of this, they are known for being the craftsmen of the Genie. They will spend years using their magic to intricately create everything from engraved buildings to jewelry (which they often wear). They consider all of the other genies to lack patience and self-control. They tend to be blunt and calm with their opinions. Dao are hard to anger, but when they are finally driven to it even the Efreeti fear their wraith. Due to the fact they are slow to anger, they also can be nearly impossible to calm down. A common piece of advice when dealing with an angered Dao is... leave.

The Marid are probably the most malicious and deceptive of the Genie. They delight in beguilement and illusions. Particularly wicked Marid are often considered to be responsible for mermaid sightings that result in drowning. The Marid pride themselves in their tricks and illusions, and are often associated with imps. Some have reasonable senses of humor and others have more evil ones, but almost always, someone else is the blunt of a Marid's joke. Marids have very turbulent personalities switching betwen clam, excited, and dangerous with no recognizable warning. Marids take particular pride in their appearance and consider themselves to be the most beautiful and exotic of the Genie. One way to see the extent of a Marid's personality is to insult their appearance.
