I like the concepts. The names... not so much. Goncatu could use something more fearsome, Arndulal sounds dull (it's even in his name),
Drakk is flat out uncreative, Rcanglai could use something more pronounceable and Deucathus sounds too long.
My suggestions:
Goncatu > Polemos
Arndulal > Thanatos
Drakk > Pleonexios
Rcanglai > Kakia
Deucathữs > Tipotos
All of them are simply the Greek words for war, death, avarice (with a male suffix), malice and 'nothing' (with a male suffix), respectively. It's not much, but in my opinion it's a lot better.
