Zanzibar, shush! i thought you were trying to stop your trolly arguing for the sake of arguing?
Dajoji is saying that YES there are corrupt guards. But it is very RARE. A character's first conclusions (or even second, third, etc.) should not lead to corruption among guards, because that'd sort of be like suggesting that Superman was streaking stark naked through Metropolis killing innocent people, laughing hysterically, and beating up Lois Lane. Sure, it's a very vague possibility, but if you suggested it people'd say you were mad. Dajoji is merely stating not to let real world 'realities' to influence your RP of Yliakum's realities. You must remember, the Octarchy is backed by the gods/goddesses. It's very likely they can find most 'corruption' almost immediately and stamp it out. Outside of the towns and cities is a different story obviously, but the Octarchy has made it clear that the wilderness is not their responsibility and that people are on their own out there.
