Especially since I am on principle against them making a canon Gorion's Ward in lore.
WoTC created a canon Gorion's War right after BG2 released and they killed him to bring back Bhaal when they moved the setting to 5e and resurrected the God of Murder.
But I don't think Abdel Adrian is doing to be reference by name, class, race or gender in BG3. Sarevok is already referenced though and there is a in-game book about the Bhaalspawn saga too.
