Faolán was writing his letters for about four hours, now. He had to think what to write, how to talk to each one of the Alpha's. It was a good thing he kept a record of every one in his computer, so he knew how each of the leaders liked to be talked to. It was no time to be cold. He had to have allies.
The idea of writing and not just calling or sending text messages, or e-mails was because he wanted to receive a letter in return. A letter would have the handwriting of the alpha', so, later, none would be able to say they had no idea of what was going on and that probably someone else, including their Lunas or Betas were the ones who answered to Faolán.
