Hehe, thanks, Yaz! This might be something that our Anglo-Saxon friends don't particularly have on their radar; for any Southerner, this is pretty clear from the get-go.
"Cicatriz" is "scar" in Spanish. As to linguistic bases for the Elven names, I don't think that's the case, because Mr Arneson didn't really follow a pattern with the naming of people and places. Notably, an "aster" in Latin is a flower - or a star. My world of Meleon's city of Asterion, for example, is "the city of the fallen star".
I personally always assumed that this name was another example for the "Beverage Rule" - the hypothesis where I assume that all place names in Blackmoor (like Blackmoor itself) are taken from alcoholic drinks:
