The discovery of two fast X-ray transients in the Chandra Deep Field-South, potentially associated with the merger of neutron stars, and hence the X-ray counterparts of GW170817 -like events, has sparked great interest in this novel type of transient. We undertake a search for similar objects among a database of ~220,000 serendipitous X-ray sources in the Chandra Source Catalog (CSC 2.0), cross-matching against optical and infrared catalogs. Using two distinct methods, we find a handful of potential candidates. These new candidates provide up to an order of magnitude increase in source statistics and should allow better constraints on the emission mechanisms for this emerging transient class. I will discuss the basic properties of the sample and what these might imply about their origin.
