The next item of interest is this "archeological" site. In the AoD world new discoveries aren't made in labs, they are dug out from ancient ruins and old battle sites. So when this ancient arc decorated by the long forgotten cuneiform symbols was discovered, it attracted many factions' attention. The arc is tied to the main quest, but it's an optional "item". You can beat the game without paying any attention to it or you can use it to influence the final events. You'd have to know how to power it up first, which requires skills and specific "how to" knowledge.​
