Just like real life, except small magic (like healing, elements, and defensive/offensive) exists.

Fantasy, kinda just real life I guess, but fictional.

The exact same as ours, except they were actually right about people being witches, they just suspected mostly the wrong people. Magic does exist, but it has been kept secret for ages, so when Iris finds out she is a witch (not really a witch, more like enchantress), she's very, very surprised.
Some factions (really just large groups of magic wielding people) that have magic. Some of them are allied but some of them hate each other. At this point, there are two main groups that have hated each other for centuries, and are still fighting. When Iris gets pulled into this, she discovers that Stella is on the opposite team as she originally gets pulled into, and starts to see her as being on the bad team, the wrong team.

Same as ours.

Same as ours but MaGiC.

Only a few selected people are magic, mostly through genetics. Mostly small magic like healing small wounds, slight amount of elements, some mind manipulation, easy future telling, ect.
