No matter where you go, people are afraid of you due to your reputation. When you are in a civilized settlement, you can get away with minor criminal offenses, such as refusing to pay for food at a tavern or breaking down doors at a local shop, since most people will not report your activity to the authorities.
You can always find a place to perform, usually in an inn or tavern but possibly with a circus, at a theater, or even in a noble's court. At such a place, you receive free lodging and food of a modest or comfortable standard (depending on the quality of the establishment), as long as you perform each night. In addition, your performance makes you something of a local figure. When strangers recognize you in a town where you have performed, they typically take a liking to you.
You have a military rank from your career as a soldier. Soldiers loyal to your former military organization still recognize your authority and influence, and they defer to you if they are of a lower rank. You can invoke your rank to exert influence over other soldiers and requisition simple equipment or horses for temporary use. You can also usually gain access to friendly military encampments and fortresses where your rank is recognized.
You have an excellent memory for maps and geography, and you can always recall the general layout of terrain, settlements, and other features around you. In addition, you can find food and fresh water for yourself and up to five other people each day, provided that the land offers berries, small game, water, and so forth.
Though others must often endure extensive interviews and significant fees to gain access to even the most common archives in your library, you have free and easy access to the majority of the library, though it might also have repositories of lore that are too valuable, magical, or secret to permit anyone immediate access.
You have a working knowledge of your cloister's personnel and bureaucracy, and you know how to navigate those connections with some ease.
Additionally, you are likely to gain preferential treatment at other libraries across the Realms, as professional courtesy shown to a fellow scholar.
