: Yes. In Myth TFL the Trow were revived and served under
: the Fallen Lords. Presumably it is in the Deciever's
: servitude that the Trow were so mightily impressed by
: his craftiness, coolity and general furor poeticness.
Also remember that the Trow seem to respect anyone who can kick their asses. They worked with Balor even though he as Connacht kicked their asses; it seems the only thing they regretted about it was that he was the Leveller. So since Myrdred did all this ass-kicking to them, they respect him too, especially since he's not the Leveller. And as a last example, remember how we win the Trow's aid in M2? We have to win a battle against them.
Trow mode of thought #1: It's not us, ignore it.
Trow mode of thought #2: It annoys us, destroy it.
Trow mode of thought #3: It kills us, respect it.
