Diaval

Diaval is Marchioness Eve's pet crow and can often be seen sitting on one of her shoulders. He appears to be much more intelligent than a normal crow, despite these birds already being quite intelligent animals. Whether he actually is a crow is up for debate after he transformed into something resembling a dragon to chase Leh'ct through the streets of Haven City.

Welcome to Haven City Arc

Diaval was first seen in Marchioness Eve's company when she spoke to Olympius about changes to the Crows security division. He noticed a spider, which was a familiar that Leh'ct had sent in to spy on the conversation, and tried to eat the arachnid as it fled under a door.
Later, when Leh'ct was brought before Eve, his mistress opened a window to let him inside just as she told Leh'ct she was aware of his previous spying. When Leh'ct used a magic spell as a distraction and made his escape, Eve sent Diaval to chase him down. The crow transformed to resemble a horse-sized dragon in the process, with Leh'ct narrowly escaping by using the last of his magic to hide his presence.
Diaval did not participate in further pursuit of the adventurers, instead being ordered by Eve to use his large size and strength to rescue her servants from her damaged mansion before any of them were further injured or killed by the plant life Leh'ct had unleashed.
