Answer my complex questions?

[Zaphyer]

1.) If Nilbog or Rogean ever decided to call it quits, would everyone lose everything?

2.) if a mob runs away from you're camp and you have to chase it down and kill it....
Are you losing you're camp?

3). Anyone ever witness a Cloaked Dhampyre being trained to Mistmoore entrance?
or maybe a story of a rare mob being trained to entrance somewhere else in Norrath?

4.) How long can a Cleric solo? Strictly no groups, duos, but just solo. Could they do it to 60 if they wanted, even though it would probably take... years maybe?
