A Warlock patron Option.
Some beholders manage to turn their madness and hatred of others into tyranny and oppression. Rather than live alone in solitude, these so-called eye tyrants enslave creatures that other beholders would slaughter, and use them to establish vast empires to rule over. An eye tyrant sometimes sets up its demesne underneath or occasionally even within a major city, overseeing and commanding networks of operatives that do their master’s bidding. You are one such agent, but not one of the rank-and-file. You are far more valuable to the beholder as its eyes about in the world. While your patron sits safely in its nest, you travel the world seeking out information valuable to your master, and are always on the lookout for its enemies. In exchange for this service, you are granted special powers, the powers of a beholder.
