Your not far wrong there =D> Prifddinas Prif is the welsh word for a prime (another word for main/capital) , dinas on its own is city so basically its capital city which as ingame its surrounded by walls and has a big gate it could be the elf capital :-k Tirannwn Tir is welsh for land/ground/territory annwn is welsh for the underworld/abyss/hell so it could mean anything like land of the abyss or something :uhh: and for the record isafdar means lowest, which looking at the map considering most of that part of the RS world isnt shown, it could mean lower territory :-k so the elvish names could derive from the welsh language :)
