I am using lore here from my own setting that I run, where stuff like the starwall is *only* described in flavour texts. This cosmos model is something I have never written down in OOC texts, but entirely in flavour texts (those who received the void lore will get what I mean). In that setting, one of the main sources for information of the makeup of the cosmos is a book written by an astronomer/philosoph. How else would he have named it? When naming stuff that is within creation, and described by beings from inside creation, I usualy name stuff right after how they look. Wall of Stars, Veil of Stars, Starnyagard as the elves say (my elves speak norse, because why not). I only make up bogus words for names that are not rooted in in reality, and even for those I have wordly names. Flowery descriptions are quite common. The only other naming convention I have is in scifi-games I run, where instead of flowery descriptions, things are usualy named after whatever scientist wanted to be remembered for discovering that shit, in this case you may also refer to the wall of stars as the van Brouwers Edge.
and since you are the only one who actually got confused and subsequently angry about it being named that way, I'll gladly continue to call it wall of stars, because damnit, it's my favourite name. Like Elf has his fanfics, I have my lore flavour texts. I just recently sent Elf roughly 2500 words of nothing but flavour texts, and those were only very hastily translated into english because I was growing tired. The original is more than thrice as long.
