Otherworldly Patron: Ancient Construct (Patreon)

You have made a pact with ancient construct. Your patron was constructed was created by an ancient civilization in an era of high magic. What the purpose of its creation was has been lost to time, but its memory is ancient, and it has many secrets to share.

The pact you made allows you to conjure protective wards, unleash powerful magic, and even replace parts of your body with constructed ones, as you slowly become a construct yourself.
