At his point in FG lore the dead 3 are back, and Bhaal, Myrkul and possibly Bane (it's less clear for him) are physically present in Faerun. Larain have teased their involvement though and
you get a camp follower that's either Jergal or an undead priest/servant of Jergal who has inexplicably (so far) taken an interest in you
. Also,
the absolute's unholy symbol looks an awful lot like Bane and Myrkul's symbols and seems to order her followers to commit a lot of seeming pointless murder
.
