On Susano, I thought his summoning to be much the same as Odin, too.

Odin is curious in that, despite lacking a circle of "worshippers," their is still the legend surrounding him and his sword. Omega's use of old fairytail creatures made manifest adds a bit to it.

People don't "worship" these ideas, the character and myth, but people still think about them. Children believe in fairytails, adults love to relay them. Odin could be the star of a ghost story.

It's a thought.
