You get everything from either the BIOGRAPHER or HISTORIAN levels, and also a custom scenario for Companions' Tale, created with your input. The scenario will be printed on a card, and added to the game.
A custom scenario (about 500 words) would tweak the rules of Companions' Tale slightly to take things in a different direction and highlight different themes.
Become one of the Companions! Your portrait will be illustrated by Daphne Hutchinson and added to the game's Face cards. Your contribution will literally define the face of the companions in games to come.
In addition, you get everything from the LOREKEEPER tier.
