Brave & The Bold Batman & Wonder Woman (2018) #4

Elatha may have been the most recent king of Tir Na Ng to die, but death is never far from the throne. Batman and Wonder Woman learn about the realm's first king, his mysterious silver arm and what bearing it may have on the problems of the present, as the Fomorians grow increasingly weary of these strangers and their questions. The duo's investigation was supposed to bring answers and keep the peace, but it might burn into the spark that ignites the first shots of war!
