: So which of the
: Fallen is most associated with undead units like
: Thrall and Shades? The Watcher.
Shades, yes (see my other post), but thrall? Hardly.
Thrall heavy levels (I mean a really sick number of thrall, not a few dozen), and which Fallen you're dealing with. Haven't played Myth single player in a while, so this'll be a little rusty.
Seige of Madrigal: Shiver
Flight From Covenant: The Watcher mainly, but Soulblighter was in the area
The Five Champions: The Deceiver
Shadow of the Mountain: The Deceiver
The Road North: Unknown, but The Watcher and Soulblighter were both in the area
Across the Gjol: Soulblighter
In Myth II, The Watcher is dead, so any Thrall-heavy levels are irrelevent.
This is pretty inconclusive. If anything, it suggests Soulblighter was the maker of Thrall, since they return in Myth II. However Soulblighter is named alongside Bahl'al, so he can not BE Bahl'al. Interesting to note, however, is that after The Watcher's death, there are almost NO thrall (in TFL at least). This could just be for challenge, but it could mean something, too.
