Maester Laes

Maester Laes was the maester of Castle Cloverwood that Lord Mikel claims 'abandoned them' in 297 AC. 
Septa Jan states that the former maester was sent away due to "having no stomach for our Lord's wound". This is in reference to Lord Mikel's chronically infected leg.
Laes may be the same person as Maester Elias, who was mentioned by Ser Valon. Laes was mentioned by Lord Mikel in a drunken state.
