This dangerous artifact has a mind of its own, and it is an evil mind. It communicated to us that it detests weakness. If our Hideout gets invaded, and we won't manage to get rid of attackers within 13 turns, it will explode, taking a good chunk of the base with it. Any operation to get rid of it would have to be performed with utmost care lest we rouse its suspicions (and thus will be very costly).
