I love my gith mage and am planning another goth character. But I made her a Githzerai in my head that accidentally stranded in Faerun as a child after some portal accident. She poses as Githyanki to not antagonise Lae'zel ( and later tells her the truth). That is my explanation,why she knows so much about Faerun and is not as accepted among the goth she meets. They can see, something is different.
