Hearing Jaroth's suggestion, Anniston bellows back up the hill, "Jaroth, by the Light, do not attack until their intentions are clear! I see twenty-five horsmen approaching slowly. Perhaps they will parley!"
Then Anniston kneels and summons Agustus (his paladin's mount). His intention is that the mount will arrive running around the side of hill rather than "poof" appearing right in front of him. ...but whatever the DM should declare. Anniston is beyond worrying about finesse at this point. It is more important to get out to support Vorian than to worry about style.
