Theotimos

'Theotimos was an old scholar and historian of the Library of Alexandria and a member of the Order the Ancients. In his prime, Theotimos was considered one of the greatest orator and sharpest mind of the Order.

After Theotimos discovered a scroll mentioning a Medjay conspiracy, a plan to led an uprising against the new order in Egypt, he made the mistake to share his discoveries with the younger and ambitious Raia.

Seeing an opportunity to increase his greater standing within the Order, Raia hired the lethal Bion to track and exterminate the last remnants of the Medjay bloodline before they could rise. Not wishing to share the glory, Raia also had Theotimos murdered by a gang of thieves in what appeared as a theft that went wrong.
