Finally, another option.
It has been six years since Federico died, and Vongola has been without any heir ever since. At first, Timoteo had turned to Iemitsu's son, Tsunayoshi, but the seal which had been placed on him as a child had damaged him too much. He would never make a suitable Don.
Thus, he had turned to searching for the results of bastard lines. Sesto had been infamous for his affairs - he had assumed there would be many.
Unfortunately, it appears someone else had tracked them all down, first. And then killed them.
Thus, the Ninth had been forced to look... closer to home, in a sense. He had not wished to look into his own late sons' affairs, but needs must.
He had expected to find Federico had sired children. His most charming son, the laughing child, the lover of women. But no, Federico had been careful - the only possibility he can find is the young heiress to Donna Giglio Nero - and even if he could prove it, he could not take her.
He had not been expecting to discover a result of Enrico's indescretions. His eldest son was married, but had never had any children by his wife. Quite honestly Timoteo had suspected he might be incapable of siring children.
But, as it turns out, his suspicion was unfounded.
There are two. Twins. A Wrath Sky - and Timoteo shudders at the thought of bringing another of those cursed souls into his Family - and a Clouded Sky. Neither is a great option. But they are better than nothing.
He calls for his Guardians - he believes it would be best to send some of them to meet with his new heirs in person.
