Bastion - neutral:)
Haven - neutral:)
I can't say anything about a good castle - this question is not for us and not for NTG;). Grove (city of night elves) may be good, but I'm not sure. Forge is definitely not a good castle :) I even think it's unlikely to be neutral; it will most likely be evil (as it's the creation of necromancers).
