I'd suggest a history command to be added that would be designed to be available to other players, rather than solely immortals: rumours.
Rumours would work exactly that history, personality, and purpose, except it would show up publicly in your 'bio'. What would you put in the rumours? Essentially, any information that other characters might have heard about you, which could range anything from being disinherited from your father to having a vast collection of globular glass objects.
More importantly, it could serve as getting people involved in your roleplaying arcs. Let's assume your character has an interest in alchemy and is trying to figure out the secrets of transfiguration. Well, put a paragraph about it in your rumours, and now like-minded folk can see it. Et cetera.
