-sliva-: Well the title is self explanitory but krewlod castle would contain a barbarian king and all castles would hold a king. You must defeat the castles king before you can take it. Once taken and owned by a clan,they can purchase only 1 king. They wont drop items or give xp,to stop intentional mis-use of them. There strength,dex an other stats can be reflective of the strongest player in the castle at the time. For s2 it has to have a basis on player level at the time of the attack.
