[DarkRanger]

Right now all temples get the same aid, based on alignment, with neutral having a chance of receiving either good or evil aid. Evil aid used to be a hellhound, which would make slightly more sense than a dretch for your character. You could guarantee a blink dog by making your alignment good, but actually that Thorn looks like a good idea for your second aid since that's when you start getting human shaped planars(tiefling for evil, no clue on good, or if it's the same). Though I'm not sure where or if reworking temple aid would go on the priority list.
