As Seneschal of the Heterodyne, and with Spark Roast being as good as it is, and Vanamonde von Mekkhan liking it as much has he does, he has evidently created a coffee minion position, the Siege of Mechanicsburg.
Possibly relevant outside information Edit
Shortly (about a month) after the coffee minion appeared in Girl Genius, a very similar coffeenaut appeared in the (at the time) new webcomic/graphic novel Power Nap. (Is this a shoutin, or does it come from somewhere else? Although the coffeenaut is a very minor character in Power Nap, he does have lines and recur and recur.)
