I recently started a thread entitled Catfolks in the Realms, due to one of my players desire to play one. Well, it's 5 hours to gametime, and he has changed his mind and decided to play a half-dragon instead. So now my question is, how would half-dragons be treated in the Realms (and Cormyr in particular). It must depend on the type as well, I mean, a half-red dragon is surely more suspicious than a half-gold one. The last time I checked, he talked about making a half- shadow dragon half drow... I would suspect he needed a Hat of Disguise or something to avoid being arrested on sight...
We had a previous party that included a full drow and a half drow and they nearly got attacked by a party of dwarves we'd encountered. It was both my cleric getting in between the two groups and a dwarf in the back doing a detect evil to keep from there being a massacre.
