The names in CR 4 are so good. Here are some fun things I noticed.
The name Lloy is a reference to "alloy".
Zebani Halovar’s name is likely a reference to Zabniyah, angels called the “wardens of hell” who carry out torture on the souls of the dead.
Occtis is the eighth son of Primus. Primus or "prime" typically indicates "the first" and "oct" the eighth.
Ethrand being another Tachonis son’s name means the naming convention may be after gasses since "eth-" is a prefix within gasses, being the second. In this case "oct-" is still the eighth.
The name Bolaire could refer to bolar earth, which is a ferruginous clay purified by grinding in water and then decanted. Lethalia contains the term "lethal" and wearing the mask proves lethal for many.
Azune's name may be a reference to “azure” which is a term used to describe the blue of the sky, typically.
Wiccander is a reference to a candle wick. The piece of the candle that burns and produces light. Additionally, you can be “burned down to the wick”.
The last name Halovar includes the word “halo”
Felonious is possibly a reference to "filament". And also, yeah, felon.
Godard is pretty clearly a play on “god”.
Aetheon means “burning”, “blazing”, or “shining”. Could also be a reference to “aether” or “ether”.
Thjazi is the name of a god in Norse mythology who could could transform into a giant eagle. He had a daughter named Skadi.
Alogar’s name may be a reference to "allegory".
Hal and Hero play lyres. Hal now carries Thjazi’s weapon, the Liar’s Blade.
Vaelus wears a mourning veil at all times since losing her god, Sylandri, the goddess of life. (Personal note: I played an astral elf named Vela in a spelljammer campaign. Vela meaning "candle")
Could Mag’nesson be an allusion to “magnanimous” which means to forgive a rival or less powerful person?
Toying with the idea that Davinos is a play on "divine".
Please tell me other things y'all may have caught. As a name nerd I am eatin' good.
