Lungorthin ("White Demon/Fire"?) - he alone amongst their terrible number was encased in pale flames. Drawn to Melkor's splendour before history he was entrusted with the infamous role of Master of the Guard beneath Thangorodrim. Rarely above ground, he spent almost all of his time in Melkor's hellish throne room at his master's side. His fate is unknown, though it is likely he perished during the destruction of Angband.

Luin or Lun is also used by Tolkien in
earlier work as meaning "pale blue" or just pale, shadowy etc.
Gorth, no doubt here, is
the Sindarin word for horror.
I derive by conjecture: Lungorthin - a name from ancient times - would mean pale horror, or horrific shadow.
Creating alternates in Quenya results from combining:
pale: marya, malwa, helwa
shadow(y): luinë, lumbë, urko
Thus I suggest as combinations for creating alternatives to
Maryarucin, Malwarucin, Helwarucin, Luinerucin, Lumberucin, Urkorucin.
Or use the specific Sindarin derivation from rucin for balrags rauko, preferrably in conbination
Urkorauko, for instance, is very nice, as is Raukoluin.
