NeoAleksandrya
From Warhammer 40k - Lexicanum
NeoAleksandrya was an ancient library that was wracked by vicious radioactive storms, at some point.[1]
Trivia
NeoAleksandrya is likely a reference to the ancient Library of Alexandria. It is unclear whether this is also a reference to the same location in-universe on Terra or whether it is a similarly evocative location elsewhere in the galaxy.
