Something that bothered me was how giving commands to demons works.
When Tom was commanded to take a message to the other wizards tower Lenamare gave him a pretty specific command appearntly trying to keep his possible actions as narrow as possible (Though he missed a few loopholes anyway) which basically boiled down to take this message as quick as possible, come back as quick as possible, don’t hurt anyone. He then put a compulsion on Tom to make sure he came back by a certain time.
My problem with this is if Tom couldn’t disobey the commands why put a compulsion on him? If he could disobey (Which by his actions it appears he indeed could) then why bother to try to give him such specific instructions without the compulsion to insure it and why not make the whole command part of the compulsion?
