As Elena breath deeply as the zombie attempted to bite her, she looked at it now that it was just a pile of ashes and shakes a bit.
"Thanks Robert...." she says before seeing his arm and how it was reacting. She looked at him worried now. They had freed the group but with the injuries Robert had taken.... She rushes at him.
"Woah easy there. You are not gonna go on in battle while in that condition mister." she says looking at his left arm. She then feels a strange energy inside of her. She slowly moved close and moved the left arm back to where it was suppose to me. She then started to pull out any dark energy that was in there and started to use the energy she was feeling, the arm slowly starting to reattach itself on Robert, threads by threads. After she was done, she fell on the floor, out of energy, breathing deeply now, feeling weakened. The arm itself was healed but it was still fairly weak.
"We need to take a minute or so just to be sure that everything will be fine" she says, breathing heavily as if she just did a marathon. Healing magic.... she had healing magic... That was really... strange. She needed to rest up a bit though cause that took more energy then anything else.

Deravan fallowed Robert, making it easier for him with his own magic as the group continued to travel underground. He was at the moment listening up, trying to catch any conversations that might talk about their own location. If so, then he would need to strike right here and now to keep the element of surprise. A good earthen strike to piece the guards right in place with stones might do the trick if they don't have their guards down. Though these guys might have magic also. They needed to be sure about everything and keep quiet. Anything to tip them off would send a alarm and that would be very bad. 
"Careful guys..... don't move the rocks too much." he whispers in a low voice, working hard on keeping the movements hard to detect for any guards that might be more awake then the others. They might take it as a small earthquake if they were to move the stones everywhere at once. That what he might do to make the guards just think as it as natural... but that probably would fail.
