There is word that you addressed the village at large with an announcement in which you claimed ownership of the library and meant to control the circumstances under which books could be taken from its shelves. If I am not mistaken, you said to others that in the world whence you came, humans used the materials you guarded to selfish and evil ends, taking advantage of your willingness to grant them access. To no surprise, the humans of Luceti resisted your efforts and the materials from your library were stolen.

[He considers the vial of blood Loki had left in his possession.]

You did not take well to having that which you love torn from your grasp. But, despite your valiant efforts, you were subdued and offered to the Malnosso by the humans, who wished you to become… docile. More easily controlled, if you will, so that they might more easily take possession of what was once yours. You were then stripped of your memory and returned to this cage in your sorry state.
