There's nothing more annoying than preparing to cast a spell, only to have it interrupted by some unseen force. After the fourth time, I knew it couldn't be coincidence and I sent Keb'ezil out to investigate.
I guarantee you'll never encounter an imp that talks back more than Keb.
Anyway, he managed to find the source of the problem, a pesky creature known as a warp stalker. They have a habit of disturbing the magical energy wherever they blink into existence. I've had enough of their interference.
Keb'ezil wants to know if it's safe to hurl a fireball without embarrassing himself again.
<The imp makes a few clicking sounds and the warlock turns toward him.>
No, it wasn't my shadow bolt! Take it back, you overgrown pixy!
Keb'ezil is relieved that you've taken care of that little problem, aren't you, Keb?
<The imp ignores its master, presumably out of indignation.>
You'll have to forgive his bad manners. You know how demons can be...
