The world is vast and infinite. It would take a million lifetimes to see it all. Yet some thurst for more adventure, more exotic calls. Beyond the world are other worlds. And in these worlds live strange beings, oblivious of our insignificant concerns.
Yet, once in a thousand years, an arcanist succeeds in making contact with the other planes, seeking unbelievable knowledge and strange company from the far reaches of the great unknown. Sometimes, they even bring something back with them.
Her "eidolon", she calls it. You ask me, that thing gives me the creeps. Every time it shows up, it looks different. Another arm, another mouth. The darned monster sometimes even shows up all jumbled, body parts sticking out where they shouldn't. What does it want really? Never heard it speak, but I can tell there's something wicked in its eyes.
