Luka, Ashley, and The Crow--as you pick up the cards in front of you, that sensation of sympathy you felt coming from them intensifies. In your mind, it feels like the the thrumming of some great string under tension. Power--energy--change--held fast but straining against its bonds. Like a bridge cable, supporting the weight of a hundred speeding cars--or, it might be better to say, a dog straining its leash when it sees its owner.
Santana considers the two holdouts for a second with unreadable yellow eyes, then shrugs. "Why you? Well, it had to be someone. And today? You're someone." He chuckles at his own remark, then his expression turns serious. "I'm jokin' with you, but that's the truth. How I brought you here, offered you a second chance at life... Well, that might have given you some more grandiose ideas of what I can do than are borne out by the facts. The truth is that, at the moment, I'm at my nadir. Even if I weren't, there are rules that beings like myself have to follow. Proprieties to be observed." He meets Ashley's eyes. "You talk like I could have picked anyone I wanted but, at the end of the day, I couldn't have picked anyone else, any more than I could make you take my offer now.
"Still, I get where you all are comin' from. And I have no intention of throwin' you to the wolves unarmed." He reaches out, grabbing Emily's card and setting it standing upright on a corner, then flicks it, sending it spinning on that tiny point. Emily, you feel an uncomfortable fluttering sensation in your chest as the coruscating colors flicker back and forth. At first, you think you see an image in the shifting patterns--a woman, holding something aloft--but it's hard to focus on it, and you lose it after only a brief moment. After a few seconds, the card slows to a stop, and falls gently down to rest where it started.
"This place--not just my domain, but everything around it--is at the intersection of reality and imagination. Between mind and matter. It's real 'cause your minds make it real. Not 'you' you, everyone. The collective unconscious of humanity is a force like gravity, and it holds together both my world and yours." He places a lime and a cocktail cherry on the bar a couple of inches away from each other. "Just like the Earth and the moon, the force of humanity's shared emotions keeps this world and yours linked." He starts moving the cherry in an elliptical orbit around the lime. "Chugga chugga, choo choo, it keeps looping around. But the effect ain't just one way--just like the moon affects the tides, the world of dreams pulls on the collective unconscious." He spins the lime, and it begins to rotate in time, keeping one end pointed toward the cherry's orbit.
"For the most part, that's all for the good. Everything in balance, et cetera et cetera. But sometimes, people break free of the spin. For some, all it takes is bein' made aware of the cycle. Other people need... more of a push. Either way, when that happens, some of that energy they contributed to the cycle is redirected. It becomes a representation of their soul, and provides some protection against the pull of the dream world. Not just that, but it lets its master exert some of that gravity I mentioned to make changes in both worlds.
"The people you'd be goin' up against already have this power. Different people have given it different names over the years, but they call it 'Eidolon'." Santana folds his arms and nods at the cards. "If you accept my deal, that's the power you'll have too." He shrugs. "Will what you gain be enough to do what I'm askin'? Well... I'd say that's up to you. I won't lie to you--your opponents will be more numerous and better trained than you. You're gonna have to be quick and clever if you want to survive, much less succeed. I guess my question is: what do you really have to lose?"
