The Ascended faction regards Basilisks as misunderstood creatures. They prize Basilisks highly as messenger birds and scouts.
Basilisk are surprisingly intelligent once trained, are able to follow commands, and can communicate rough information (like whether or not enemies are near). They can be perfectly gentile and orderly when kept in captivity.
This is all despite their somewhat gruesome appearance and the fact that they can spit venom over a 5-meter distance. Some Basilisks have even been known to laugh and quack when its master does, giving the impression that the Basilisk cares for and empathizes with them. So, never ones prone to judge a book by its cover, the Ascended champion the Basilisks as great pets and working beasts despite their terrifying appearance and the hatred the general population has for them.
