Claudius
The very common Roman name Claudius puns with Greek κλειδος kleidos for “lock” & “key”, which is found in the Semitic languages as קלד qld for “locked up” & “disappeared”, and as קלט qlṭ for “protection” & “shelter”. The name would befit any spook whose true heritage is “locked up” & “sheltered” from public view.
This word root seems to have gone back & forth between all Mediterranean languages. Judging from the attested meanings, my best guess is that qlṭ is the original Semitic form, which was loaned into Greek, and then back as qld.
This pun may also explain the Greek name Euclid.
