I really like the new thoughts/interpretations of the "Good Night" greeting and Orolin's name, Jeremy. For me it sounds comprehensible, harmonic - and with an alien touch.
About the Wolfrider soulnames: I'm going with the assumption that they are incomoplete, multilated - as it is stated in the BoTC novelisations.
This way soulnames would never give a complete information - only one word of several, a sylable or a "cut-out" of the complete word. In example (no "true" meaning intended): As a pureblooded elf ...
Zash would be Za-shen or Cuz-ash or Min-zash
Twen would be Ka-Twen ot Kat-wen or T-al-wen
You get my point? The name leaves doubts ... makes it more complicated - or can be a chance!
