Hellpower will astral mark all the mages involved in a communion. And I think you will need several castings of horror mark to exceed the marking from hellpower.

Personally, if it was just a small number of SC's I'd gamble on the charm working and ending combat before the horrors show.

OR

What can be fun is Ritual of returning bringing your entire communion back - but leaving berserk maenids...

And pray the horrors show...
