Always crack up at "Albs"
It's clearly a variation on Elves.
They're basically the same concept as high elves: emotionless, aloof, believe they're superior, have great knowledge and magical abilities, etc. Except in a sci-fi setting.
Alb is the old Nordic word for Elf. The old high German word is Alb aswell.
By now Albae have become mostly synonymous with dark elves in Germany, mostly due to the success of books written by Markus Heitz.
He is one of the most successfull German Fantasy writers. Not really something special, on the quality of better published DnD books, but thats it, but very influential.
His version of the Albae is basically lifted from DnD drow anyway.
So you are on the money, the Alps in Elex are supposed to be elfs, specifically drow.
