Well, the xp was divided 7 ways. I figure the king and his illithid cleric probably accounted for 1/2 that (CR 20 and 19 respectively). The rest, like I said, it's a converted 2e module, so there is probably some arbitrary amount of xp the party gets for finally destroying the city. Knowing 2e, it was probably like 75,000 per character. Our DM just houserule'd it to some smaller amount for 3.5.
As for the TPK... apparently the king suffers from some racial insanity that makes him less than lucid when attacking in combat. So the party was able to keep his attacks on one tank while the other tank got healed. The clerics both died because they had to get inside his reach (10' due to Righteous Might, which we never managed to dispel) to heal the tanks, and then took a full attack. The druid died when he turned into a dire bear and attacked the king, who promptly turned around and owned him. The arcane archer and the sorc never got within 30' of the king, so they came out fine. Our ranger/fighter/horiz walker had a cloak that cast [/i]stoneskin[/i] on him, so he could take a few hits, and the dwarven defender.... well, he had over 200 hp while stanced, so he could go a few.
