Reverin spun around on his feet, but somehow continued moving towards the now faintly visible stone chapel at the edge of the forest. He pondered his choices before responding to the orc:

"Perhaps I simply require your services because I do not wish to waste time casting summoning spells. Perhaps I am bored of using my own servants and would like to enjoy the sight of others fighting for me. Or maybe it costs me less gold to hire a few slabs of muscle than it does to summon powerful allies. What is it to you, orc? You get paid, and you fight. Isn't that what your...people do?" 

There was clear disgust in the mage's voice when he referred to the green man's kin. Reverin continued to glide along the grass, courtesy of his minor flight enchantment provided, amongst other things by the faintly glowing silvery ring on his finger.

"I wouldn't concern yourself with my grand plan for this encounter; your job is simple: fight. The tactical side of things has been taken care of, I assure you."

The energy emanating from Reverin wasn't particularly hostile towards the half orc, but one so inclined or magically enhanced could clearly sense undertones of selfishness and perhaps even evil lining every word the mage uttered.

The oddly heavy sound of footsteps on grass caught Reverin's attention before he even finished speaking, and now his attention was squarely focused on the newcomer. The wizard couldn't sense the motives of the human, but the lack of magical aura around him washed away any sense of danger the mage had.

"As I said, the tactics have been taken care by me," reiterated Reverin to the orc, nodding towards the human.

"It's good that the lady referred you back to me," he spoke to the human, drawing on his best manners to force a polite smile. "Slipping away won't be an issue, I shall only require your services for the next few hours or so. You come with me, you fight and kill, and you get paid well. That would be a good deal for any paid mercenary, and it looks like it would be especially useful to you! Come along now, I will explain on the way." 

As they neared their destination, an old grey chapel seemingly long abandoned and in ruins, Reverin briefly explained the requirements:
"All you two have to do is ward off any enemies that try to attack me, and take any opportunity to attack that pesky enemy mage Erepar. Don't touch anything on his person, lest you want to be cursed. When he is dead, you will get your payment and be on your merry way."
