Máire Laidcend is Brighid Laicend's aunt. When she died, she left her house on Éilís Mór to Brighid. At first, Brighid was grateful, but she soon learned that Máire concealed a dark secret. That dark secret made her regret everything, and probably set her own house on fire. It's impossible to be sure of what actually happened to Máire, but it's clear that she came into direct contact with the overwhelming darkness and evil found past the veil, probably through the Cronemeadan. Thanks to that, she became corrupted, assuming a bird-like physical form, which can be seen on her coffin. A monstrosity.
