When Elie and Alfirin next return the Marian Leigh preparations are in their final stages.
There's a map of the city, done by magic, with brightly colored flags for various objectives, and an operational timetable, and squad assignments and a schedule for pre-combat spellcasting which starts with contingencies cast days in advance. By the day-of the schedule details who does what each round for four full minutes before they head out. Elie has two paladins assigned to him whose main job is to keep enemies off him and tank spell effects for him with Paladin's Sacrifice; Alfirin does too; they separately each have a cleric and a song-sorcerer assigned to them.
In case Elie is unfamiliar with the main personally powerful combatants of the Shining Crusade, here they are and here's their deal.
The Mirrorgrave has an artifact cloak into which he directs all hostile spell effects, best to let the people with swords handle him, he can also vanish and leave behind a statue of himself, it is considered worthwhile but not high priority to blow up the statues because it's thought he could also return to them.
Kavasa is an incorporeal banshee fifth-circle song-sorcerer whose screams, as you might expect, kill anyone who hears them, and override Silence though not a sufficiently heightened Silence; in general everyone will have Death Ward up but anyone without Death Ward up should probably deafen themselves.
Taldaris, Saravega, Quarnim Ix, and Magallentis are all eighth circle wizards/sorcerers and are also liches. Taldaris has some fancy magic items and some genuine cleverness as a commander; as a combatant he's not that much scarier than a normal eighth circle caster. Quarnim Ix merits particular note, he's a Blood Lord of Geb and has some weird tricks up his sleeve and casts as a sixth circle cleric as well as an eighth circle wizard.
Kritasheere is a ghoul and the ninth circle high priest of Urgathoa, insofar as Urgathoa's Church can be correctly characterized like that. He's fond of enchantment effects, and very very skilled with them; if he lands one on a spellcaster he'll have them Teleport or Plane Shift to a dungeon of his to be made undead. She mentions this as it helps some people make a second desperate effort to break the spell.
Naraga and Istravek are undead ancient black dragons with the abilities you'd expect of undead ancient black dragons.
Malyas is a vampire lord and an antipaladin, sometimes accompanied by paladins of the Shining Crusade who he turned into vampire thralls or graveknights. He is astoundingly deadly in melee but Elie is presumably accustomed to avoiding melee.
In the same vein, Cosarra and Alamathus are very deadly graveknights, avoid melee, if you kill one don't let anyone Teleport out with the armor, it contains their soul.
Jolanara is a nightwing, which means she travels cloaked by dozens of greater shadows that drain strength at a touch and that if she kills anyone she can use their soul to build a conduit to the Negative Energy Plane, which makes them hard to raise.
Erum-Hel hopefully won't show but he's a morgh assassin, teleportation is impossible in a radius around him, he's generally invisible and doesn't show up to detections short of True Seeing, and the injuries dealt by his blade are nearly impossible to heal with magic. Also when he kills people they turn to dust, which is a going concern here because Elie might wake up in his clone back home. He doesn't stick around, generally, just ambushes someone stabs them to death and isn't seen again for the rest of the battle. He's been gone for the last five years, but killed a dozen of Iomedae's top people in the space of a week before that, she dislikes the guy immensely.
And Tar-Baphon's aura of terror paralyzes anyone within 60 feet who isn't immune to fear, he can command arbitrary undead, he has at least twelve ninth circle spells a day, he throws around a lot of empowered disintegrates and mythic fireballs which bypass fire immunity and of course he can do a bunch of things like land a Dominate through Protection from Evil or do a Time Stop that lasts long enough to search the whole battlefield for his targets, examine them closely, and have spells ready to hit them when it ends. If Elie or Alfirin lands a disjunction on the boots of teleport and then counterspell him for a moment then Iomedae or Karlenius can kill him which is always nice because he wears good gear, including some minor artifacts, and it leaves him on the back foot for a week or so.
Elie should yell through his telepathic bond when he needs his paladins to take a hit for him, otherwise they'll use their best judgment, they know about what's deadly to a ninth circle wizard.
