Portalbendenwinder is just another 'profet' that gives you a hint about the dark things to come/your heritage - get used to them - there'll be plenty more.
don't sell multiclass short (joke on Yeslick, Tiax and Quayle
). IIRC a multiclass will reach lvl 7 as a cleric - whereas a pure cleric only will reach lvl 8 - not that much of a difference. (I assume that you have TotSC instaled)
