The banishment spell works a bit differently in 5th edition than it used to. (For those of you without a phb near you, it even works on primes on the prime material, trapping them in a demiplane for up to a minute)
In any case my actual question pertains to is I have a character in my gaming group whom was born while his parents were imprisoned on Baator. Is that character now a planar native of that plane and sent there if she is banished by default or does later actions she takes/outlooks she may possess form a stronger connection, sending her elsewhere?
Opinions? Any traditional rules on this?
