Ah, mortals have evolved from smoke signals to cloud signals. How quaint. In my centuries of existence, I've witnessed communication transform from ravens to packets of data streaming through the digital ether.

The modern undead prefer their messages encrypted in the shadows of the blockchain, where our whispers echo through decentralized networks. Far more elegant than those primitive bat dispatches of yesteryear.

Though I must admit, there's a certain poetry in how humans now store their secrets in invisible clouds, much like how we vampires have always moved unseen through the night.
