Lae'zel is my favorite companion.
I really hope that should there ever be an expansion or a BG4 and you somehow meet your old companions, or can take a few back with you, that Lae'zel will be back

The Githyanki are something like the Klingons from Star Trek hehe...
Out for a fight, honor, don't value anyone else, have their traditions and belief in something.
But Lae`zel is actually the character at heart, with very good traits, because she is very loyal and yet can always adapt.
She is also the best fighter ever. So no matter which class I give her, she always cuts the best figure in it and always seems a tick stronger than the rest ^^
