Part of me wonders what V's spell did to Tiamat. Do you think she ever spawned a dragon in the balck dragon's family line V wiped out? If so, what did the spell do to her/ her black dragon head?
It clearly didn't kill one head because Tiamat is calling on 5 lines at once, and the deity rules in 3e are pretty clear about divine immunities. All deities of Rank 1 or higher (i.e. Demigods and up) are completely immune to death effects (and polymorphing, energy drain, ability damage/drain, mind affecting effects, electricity, cold and acid, disease, poison, sleep, paralysis and disintegration). If all Black Dragons are descended from Tiamat, the spell probably hit her, she shrugged it off, but was really furious about what it did.
Remember that big line of victims on the other end of the cloud for processing into heaven after the Battle of Azure City? Tiamat's realm down in the lower planes just got roughly 1/4 of all black dragons (and black-dragon kin like half-dragons) showing up at once, due to a relatively low-level mortal with a grudge being handed the powers of what appears to have been one of (if not the) most powerful necromancer to have lived on that world by a trio of fiends that knew what the possible outcome would be since they knew quite well what the abilities of each of those spirits were.
In other words, Tiamat might be really angry at V, but she's smart enough to also blame the person who gave V that kind of firepower to begin with and know that if not for the IFCC's very out-of-the-ordinary meddling this would not have happened. Might Tiamat's legions of dragons now be another side in the "War on the Heavens" the IFCC want to start, with Chromatic Dragons against Fiends, and the Fiends trying to go against Celestials?
Also, this is the important part where V actually admitted he/she was wrong, and seems to have learned something. This appears to have really been the plot arc (soon to be a book I presume) where the OotS generally grew. Belkar learned to (feign) playing nicely with others, Haley had to deal with responsibility, Elan grew up even more than the whole "Cliffport Redemption" plotline with the whole Lord Kubota & Therkla story, Roy got a new focus after training with the spirit of his Grandfather in heaven, V learned humility and the limits of magical power, and it seems like only Durkon didn't have a major character advancement of some kind in this arc.
