Beware the Tricks of Loki
God of Mischief, Chaos and Change
Master of Magic and adept Shapeshifter
Harbinger of Ragnarok and Rebirth of the Worlds
A sly, vengeful trickster who is always causing trouble among the gods, he is tolerated in Asgard only because of the great services he has performed in the past, such as helping to create Midgard and the wall guarding Asgard. He has mixed freely with the gods for a long time, even becoming Odin's blood brother. In his true form, Loki is a handsome young man who is always dressed in some combination of red and black.
The whole thing sounds kind of bleak, but it has always seemed to me that figures like Loki have provided a necessary function. Without tricksters such as him, the world would become static and unchanging. I can hear you saying that there are innovators and revolutionaries, who serve much the same purpose, and they do so without causing all kinds of trouble or destruction, but that probably depends greatly on who you ask (and how their worldview is on who the “troublemakers” and “tricksters” really are).
Loki's children are powerful being that have power to aid or hinder the gods and mortals alike.
