au dean/castiel; angel!castiel and prince!dean

[kruel_angel_lj]

The bits and pieces I remember are: it's an au, Dean is a prince (John is the King)? Cas is an angel. The part I remember is Cas picking Dean up in a forest(?) and flying him out of there and that Dean is afraid of heights. That's all I got, anyone know which story I'm talking about?
