"A circle that summons Niyar and [i]only[/i] Niyar," the hundi said, inspecting the sheet of paper, nodding, and then handing over another blank copy. "The difficulty in modification is the point."

She stood up, leaning against the demon and tapping her fingers on the staff. "Modifying summoning is [i]dangerous.[/i] The traditional circles are designed to be augmented by all sorts of ritual to provide the power needed, and the beginner summoners there are protected by their own lack of power. If they modify something without understanding, taking the broad instructions given and pointing to something else... it will probably take no notice. But even then, you must know the stories--a weak apprentice tries to summon a fey for help, but botches it and calls forth the unseelie and a far higher price...

"Someone with the strength to be a true mage is even more in danger. [i]They[/i] can skip all the ritual, the strength of their call no longer limited by knowledge. The stories of a foolish child who hastily modifies a circle that barely described a sex demon in a search for vengeance, and calls forth something far... more. Something the meagre protections they created cannot hold, or maybe they thought that through and instead make a deal at a price far too high," Gisela shook her head, pacing a little. "So, I created these circles. Without intimate knowledge of what you hope to summon, then they cannot be modified successfully. Even if far more mana is used than they require, it only strengthens the bindings.

"Anyone who learns enough to change them is someone I would be happy to call a colleague rather than an apprentice. We have nothing so formal but the same principals apply," she finished. And, in the case of this one, maybe the experience would teach her how to negotiate with powerful entities without offending them. "Until then... well, I have circles prepared for Niyar, Lamplighters, Sylphs, Imps..."

She paused. "Oh, and incubi are mostly safe. Or succubi, whichever you prefer."
