Merrick is a Wizard of power, though he seems forgetful or senile, but his wit is sharp when focused on a goal.
His stats are unknown to the party. He is the Patron and Sponsor for the current party.
Merrick is a powerful wizard in the employ of the current town. His abode is almost impossible to find as the entrance likes to appear in different locations in the city. Unless invited or you have a letter with directions (Which do change), you will simply be unable to find his residence (Which is on another plane anyways).
Merrick took interest in the local street urchins – Gabrielle and Harold, after they were arrested. Seeming to pick them out as if with a purpose. His other motives are as of yet, unknown.
