I think there is no easily digestible information around, regarding sentinel . Although the term "easily digestible" is relative. Someone may say to you, here is the code, and it is an easy code, it is not rocket science. So it is easily digestible.
When in this strange city, some people get paid for just smiling and for just being beautifull, then you should expect that those who are giving you directions will want to get paid too. If you think it is negative to pay people that are helping you, then you are out of the spirit of the Dash Timocracy.
This is the city of Dash, this is what you pay for being a citizent of a Timocracy. This city unfortunately changed a lot since the days you used to offer information and work for free. You did it for free, but nowdays people
get paid for that.
