===============

One herald takes the portal glyph (in scoring, Grimoire otherwise), and gives his locus to the horror unit with the iridescent horror.
The other group of horrors goes in reserve and deep strikes back field later in the game.

The other herald grabs prescience, then hangs out with the screamers, flying over things all game, maybe dropping an assault later on. They have prescience just in case they get assaulted and need to re-roll to hit. This is also helpful with Lampray's Bite attacks, if it comes to that (S5 AP2, but only 1 attack per screamer).

The princes and Kairos fly around and kill things.

A little light on scoring bodies Mark? I understand that the portal glyph can spawn more ( other than that I have no idea what) but even still 2x10 is rarely enough. Then again with 3 flying monstrous creatures some opponents will have fits just trying to kill that. I think its a very rock, paper, flyer, skyfire list.
