I've made two attempts now: This is the first one, for chapter 8 of Quenta Narquelion (my Ghost Feanor story)
And this is a War of Wrath map for Chapter 12: In Armour of the Elder Days.
(Yes, I know I've missed the 'g' in Angband! I can't see a non-obvious way to fix it and I can't bear to re-draw it, so it's staying like that. Digital mapmaking would be SO much easier.)
