For the most part, Faer ignored the shouts and grunts of the fight as he cast various of spells and using the magic of his staff to fight many of the darkspawn that focused on others who were having trouble, moving on his own accord without heeding to the advice that he -- and others who apparently couldn't fend for themselves that much -- was given by the more defensively-acquired (those who were heavily protected with armor compared to a mage's nothing-but-cloth robe) people. While it was common knowledge that mages took heavy damage because they didn't have much to shield with, his Keeper had been adamant to teach him early on that they are mainly an offensive tool in forces, their spells powerful enough to kill an enemy within one or two casts before they could suffer any hits.
The other strategic thing that he thought of (as he was more focused on the thought of Darkspawn! Kill them! than actually planning out an elaborate outline on what to do) was that he was virtually left untouched and mainly unseen by the darkspawn -- on occasion of one, who had singled him out after a fight with one of the others, to which Faer finished him with with a simple staff attack. With Conlan bellowing his taunts at the darkspawn so that they would draw their attention to the warrior, the Dalish mage neither objected nor interfered with whatever the other man was doing, feeling that he was better off anonymously casting supporting spells for his fellow companions as it was the specific reason why he had chosen these magic lines than the other ones that were more heavily damaged.
Now currently stationed next to the cliff of a ledge on the right of their surroundings, after casting several affliction hexes (most of which were for darkspawn that were targeted by mages) and a few death hex for one who looked to be a rogue, he silently and stealthily moved past the fight and horde towards the road in the direction that they were heading before encountering the foul creatures, most of which seemed to be dead only after a few seconds of actual fighting. With thirteen people fighting against rather primitive (at least, he didn't think darkspawn were necessarily smart in their fighting, more just basic animal instinct) creatures counting at only about twenty, it shouldn't be much of a problem defeating their enemies.
And then all of a sudden, Faer tensed up and for a few seconds, wasn't sure what was putting him on such a sharp edge when, just a moment ago, he was feeling relaxed and even slightly glad that he finally got to deal with some of the darkspawn (that was, after all, the whole purpose of Grey Wardens.) He paused a second in his fighting, abruptly stopped in the middle of casting a horror spell at a random darkspawn to survey his surroundings, wondering if he can find the source of his nervousness that tingled in his head. The feeling was familiar enough that he could say what it was: it was someone using magic (provided by Hissra and Lillie Tharelle in previous fights), but where it was coming from was unknown.
Then, in the back and hiding by a tree, Faer caught sight of a Genlock Emissary, lifting a staff in the air to signify that he was currently in the middle of casting a spell. With a curse in his native tongue, Faer was well aware of the potential threat that this darkspawn mage could cause to their party, especially with the earlier thoughts that he had just been thinking. Without waiting, he quickly moved in closer proximity of Simon Coibran, using his staff attacks along the way to help with the fighting before he was close enough that he could shout at the Templar. "Simon!" he called, making sure to sound like he wasn't telling the other man to do something but still made a sense of urgency in his voice, "There's an Emissary over there, can you take care of him?"
