Scrivenscry

Scrivenscry is a vainglorious arcanaloth travelling the planes in search of the Books of Keeping, four tomes containing the true names of every yugoloth in existence. It always refers to itself in the third-person, has a fondness of liquorice, and has in its servitude a nervous, blind albino penguin under the awaken spell called Kingsport.

In the late 15th century DR, its escapades led it to the desolated Netherese enclave of Ythryn, where it mistakenly believed the Books of Keeping resided.
