Orinthal claims to have been a former assassin before ending up in the Shivering Isles. Now, he spends his time counting and gathering facts and numbers. He lives in the southern part of Bliss, next door to Thaedil. His house is filled with a large number of books and crumpled paper strewn all over his house. Other than the books, there is little of value. Not much is known about Orinthal, other than what he claims. It is unknown why he entered the Shivering Isles.
He seems to have an obsession over triviality. He has no major use in the game. He will continue to spread his apparent knowledge for as long as he lives.
- If Orinthal dies, his tombstone in New Sheoth Graveyard will read, "Numbers matter no more, for Orinthal has found eternity."
