Description: Portable heads are compact repositories of knowledge. Though a portable head can have any outward appearance, tinkers with capricious senses of humor usually build them in the form of the heads of various creatures (and often in the form of their own heads).
Operation: All portable heads know at least one language, in order to understand spoken commands. The most common portable heads are those with a second language installed in order to act as translators. After being activated, the translator listens to what is being said during one round and speaks it in the next. Listening to languages it does not understand confuses the head; it returns no results and lights its gemstone eyes in confusion.
More complex portable heads possess a body of knowledge on a particular subject. When activated, the user can ask the head a question. If it doesn't know the answer, its eyes light up. When it does possess the knowledge, it speaks the answer via a small vibrating membrane hidden in its mouth.
When a portable head is created, it can possess a second Speak Language skill or Knowledge skill at 3 or 6 ranks (with prices listed). Multiple languages and Knowledge skills must be added as secondary functions. Additional languages or ranks in Knowledge skills may be added to a head later as upgrades.
Spoken languages are translated automatically when a portable head is active, but multiple nearby speakers easily confuse it. When posed a question that requires a Knowledge skill check, the GM makes the roll on behalf of the portable head. If the check fails, the head does not have or cannot access the information desired.
Activating the head requires a DC 15 Use Technological Device check. Starting the head takes 5 rounds.
Fuel: The portable head uses 1 vial of liquid phlogiston for every 6 hours of operation.
Malfunction: The head provides incorrect information or a mistranslation.
