At thirty-two, veteran tank Rondo Glass is known as Forever Silver, a worn-down adventurer with a tarnished badge, patched-up gear, and no party left to call his own. But after one night of drunken misery leads him to Lydia Claystia, a legendary Adamantite Rank priest buckling under impossible expectations, Rondo finds himself dragged back toward the dream he’d all but abandoned. Between monster hordes and assassins, new friends and old, and the Guild’s dreams of dragon slaying, Rondo will have every lesson from his fifteen years in the field put to the test. He may not be the strongest adventurer around, but he knows one thing better than anyone: how to protect the people who count on him. Silver Rank or not, Rondo’s second chance starts now!
