I need you to reach into the world beyond this room, <name>. Allow me to explain.
You see the difference in this room compared to the rest of Andorhal. My dragonflight works in many different ways and in many different timelines. To mend Andorhal's damage, I now act from a different timeline as not to overly contaminate it. To continue this though I need time trinkets, ones trapped from when the plague hit. Find them in lockboxes found in the ruined buildings that make up this once proud city.
Allow me to suitably reward you with this. You may not understand what you would need with such a device. You might not even know quite what it really is. Alas, I cannot tell you when you will find it most useful; just know that at some point in the future, you may find this item to have extreme utility and function when consumed. Whether or not you choose to hold on to it until then... this, my friend, is up to you.
