[Suzerain of Sheol]

The Fall of Gondolin is kind of a mess the way it's written. It's clearly an earlier piece. The most egregious issue is entire armies of Balrogs being present, as it was only later that he made them corrupted Maiar and, arguably, the most powerful of Morgoth's servants.

I wonder if he'd still have Glorfindel, Ecthelion and the like killing them if he'd ever gotten around to rewriting it.
