Hearing Tivus' signal, Ivarlan turns irksomely from his less than wonderful tracking experience. Perhaps it was the lack of action, or his aggression from hunting the elk, but his senses were never sharper, and his body moved quickly and naturally.
Assuming he spots/hears them, which I hope he does with that roll, he'll head on over, drawing his sword in the moving process. I assume I wont appear for a round or two though. If he needs a roll to see if he's familiar with it, know that he is less so.Know (Nature): 8
