Belegarth

I need help combining these two words into one title. i know very little on word structure to merge them and they have the same meaning.

Darastrix Arytiss

they mean Dragon Warrior in, you guessed it Draconic.

Not a human language so word structure doesn't mean ****.

But, anyway:
Darytiss
Darastiss
Darytrix

Etc. It's not like they have weird clashing consonance.
