"Magic can do that?" Lancelot asked with some curiosity, "What kind of creature will be summoned? An angel?"
"Angels, demons, mortals, even talking frogs—who knows," Kalalin said with a shrug, "The key is it meets the three conditions described by the magic: the ability to help us, the willingness to help us, and the capability of being summoned by the spell. But really, as long as these conditions are met, does it matter what we summon?"
"Indeed, it doesn't matter. Even if it's a stinking orc, I'd accept it," Bruto nodded somberly, "So, what are we waiting for? Let's get started."
"First, this spell, called Otherworldly Oathbinding, has a somewhat costly price..." Kalalin said somewhat sheepishly as he looked at Lancelot, "It requires a rather precious gemstone as the casting material."
