The term Genie can be split into three different groups.
The Marid is the most powerful of the Genie family and is near impossible to catch.
The Ifrit, also called Effrit are more powerful than a D'jinn but less so than a Marid.
The D'jinn are wish-granters, but are very rare and difficult to find and capture. The easiest way to catch a D'jinn is to summon one using magic circles. They are powerful creatures usually made of fire and wind. They can be tricksters sometimes, getting their captors to wish for wrong things, which in the end would set the D'jinn free.
There are also dark D'jinn called Ghul. These are night shades and can change shape at will. Generally unpleasant, these will not grant wishes unless they have gained what they want first.
