Name is explained by the krogan expert Noivurn:

Ru'Bror - "ru" to mean "child of" aka "ru'shan"

Bror meaning cinder/fire

https://masseffect.fandom.com/wiki/Trobror <- the planet means "ash-heap", but assuming that it's similar to aralakh (lakh being "eye", so the descriptor "of wrath"/ara is first in the word, leading me to believe "tro" is heap and "bror" is cinder"

ultimately it would be a krogan word for "child of fire" which seems like something a krogan dragon might be called

I'll likely give him a nickname like Indigo because I'm bad at remembering my own creations names.

Anyway

This guy is part of the same place that was mixing genes around to see what fun things they could come up with that created Scorn, my krogan. When the krogan escaped/was rescued, he took another creation with him but didn't hang around long enough to search the whole place since it was at the time, explosively decompressing. As it turns out more of the facility was left intact and still functioning on automated VI control as best it could.

After being out for a few months and filled with questions that his rescuer Tab couldn't answer our fearless krogan returned to the place of his birth. Among other things he found a large dragon that had been twisted with some of his own genes giving it plates, a legendary krogan temper and most luckily a quad. The full story should be compiled by the time this guys reference is complete in a month or two.

Just wanted to tease y'all with him for now!

Ru'Bror/Indigo is mine.
