I'm probably opening a can of worms here (like I haven't been doing that for the past week
), but has no one who has read the Alanduo prophesy wondered about the 'score of mortal progeny'?
Who's to say Bhaal didn't avatar himself on Toril earlier than 1358DR/Time of Troubles and impregnate a bunch of women? I assumed, as I'm sure others did, that the 'they' from the rest of the prophesy refered to the children born/conceived during ToT. Maybe it refers to ALL of Bhaal's children. Saradush is supposedly a refuge for Bhaalspawn, yet Illasera and Yaga-Shura claim to have killed others of their father's blood.
A 'score' is equal to 20. Lesee, there's The Five, Sarevok, Imoen and Charname. Plus the three in the Marching Mts., Vikeig(sp) from Trademeet and the four others I found hanging out in Saradush. That's 19 I can comfirm myself. What did Illasera and Yaga-Shura kill? A simulacrum of a projected image of a mirror-imaged Bhaalspawn?
As for the original question: play Throne of Bhaal at least once. Jason got it right with going from boss fight to boss fight. I found the best part to be Cespenar, your Abyssal butler.
