Draiss nodded as his own spell finished, and softly hissed about elf prisoners being sacrifices to the dragon as he continued to pole the raft forward. This was one of the things he did not like about this part of the adventurer, putting party members into dangerous situations while he was nice and 'safe' in the back. The spell was only good for about ten or fifteen minutes, so he would need to stay out of sight once they got to the city. Not too hard as he would sneak about, augmenting his sneaking skills with his timeline knowledge to know what would happen a few minutes before it did, and should be able to avoid being seen. If he managed to back himself into a timeline event where it was either be fight or be caught, he would alter himself into a lizard folk, and follow the group to the tower.
