Penumbra appears in Telepath RPG Chapter 2.
If the Hero has high enough personality, an account can be opened with Penumbra and war bonds can be bought. War bonds bring in a 25% increase on the intial value of gold invested after each new mission is completed, but without compound interest. Up to nine bonds can be purchased at one time, costing 100 gold apiece. Before the hero can buy more bonds, the old set of bonds must be cashed out first.
"Welcome to the Somnus branch of the Shadowlands National Bond Office! My name is Penumbra. Here on business for your master?" "They don't pay me to make the rules. They just pay me to enforce them. Sorry."
"Great. What with the civil war going on, values in the war bonds market are skyrocketing."
- Penumbra will only believe the hero if their Personality is above 7.
- A "Penumbra" is the outer shadow cast by an eclipse.
