I dont really het why he is sharing precious military knowledge with them or why is he even helping Humans the moment he signed that contract with baalkaroth he should consider them a potential enemy ,the duengeon is understandable since its on his territory but saving the princess and stoping a civil war doesnt make any sense his family are arms dealers a war will benifit them the most also during war them its easier for him to employ troops to get rid of lucas which by the way is plotting against him while MC is not even training his magic properly and killing his liver with booze
