I made a Githyanki Priestess of Selune to see how Shadowheart reacted.
Not only was I disappointed that Shadowheart only reacted to my Gith heritage and ignored my deity choice but Lae'zel did not even notice that we are both followers of Selune.
Especially since I chose the option to let the party know I was a Priestess of Selune when both companions were in the party at that time.
Which is dumb, on sooo many levels... not only are Githyanki usually atheists, or if not, worship their lich queen Vlaakith first and foremost, and maybe some evil or neutral deities after, not to mention that the clergy of Selune is usually KOS for followers of Shar.
Another example for Larian not really doing their homework...
