Darren explained the limitation of his magic, and Rutger tapped his chin thoughtfully. The thick undergrowth of the forest, and the dense foliage of the trees, did mean that Darren's vibrations would be bouncing off of everything and overlapping until they were so thick it'd probably be impossible to get any specific information out of it. Fortunately, Artemis had a solution. He used one of the spells he had recorded in his book to sent out floating motes of dust, so small and floating so gently as to be nearly imperceptible if one wasn't looking for them. 

"That'll do, I think. Thanks, Artemis." the fire mage said. Looking back at Darren, Rutger had another idea. "Darren, why don't you try sending periodic vibrations through the air, straight up above us, as we move on? Artemis's Earth Magic will cover the ground, but there could be an enemy flying up above, or floating observation Lacrima or something like that. In the open sky your vibrations would be clearer and let us know before we enter their line of sight."

Turning back to Mombaki, Rutger motioned out towards the forest. "Okay, kiddo, you're up. See if you can track these guys down." He held out the map to the wild magician. "Use this, if it helps. We should be right about here. Try not to scout too far ahead, or you'll get out of the radius of Artemis's spell." He tapped a finger against the paper.

As the small group began moving through the wood, Rutger held up one hand, palm open. No flame appeared, but he could feel the warmth of his magic power tingling through his veins, gathering just below the surface of his skin. If anything got past his allies, he would be ready to hit it full force. He kept his eyes open, glancing around here and there as Mombaki led them through the shadows of the trees.

"By the way, Artemis," he whispered, his curiosity overcoming desire for stealth, "Does your book have any interesting fire spells you could teach me?"
