Vahres has seen quite a bit of Theah in his decades; he’s become knowledgeable about history not by learning it so much as living through it – he has witnessed a number of historical events by being in the wrong place at the right time; usually while expanding his knowledge of the healing arts. The base of his medical knowledge came, as it does for all the best doctors, from the teachings of the Castillian universities; he expanded upon this knowledge in each country he has visited. From the Montaigne, cooking techniques, some of which proved useful in refining medicinal compounds. Time spent as the personal physic for a chapterhouse of the Jennys’ Guild in Vendel gave him access to the otherwise difficult to acquire masseur’s skills. Thence to the triple kingdoms, where he acquired the essentials of bartending as part of a cultural exchange with an Inish scholar. From the Vodacce, perhaps unsurprisingly the lore of venoms and antidotes.
He managed to wrangle the right to travel with one of Bernoulli’s caravans that trade with the Crescent, and if one is to believe him, managed to impress them sufficently to be permitted to study their arts – and their collection of collected Cathayan works; the latter being the far more impressive feat by far; though not even he has claimed to have ever actually managed to visit the country proper; from these tomes he has learned the first steps in the the foreign and often mystic-seeming art of acupuncture – which appears to involve sliding long needles into the human body to cause it to relax.
Neither are the islands of the midnight archipelago terribly strange to him; he has demonstrated the ability to communicate in a number of the local dialects. Here too, he claims to have expanded his medical technique; in particular his botanical knowledge, herbal lore, and several of the native cures from the various savage shamans of the isles.
There remains little of the world he has not seen; yet even now, when his contemporaries are retiring (or going into hiding from the Inquisition), Vahres continues his journeys, ever seeking outward for more knowledge on how to mend inward.
