Half an hour later and a number of interruptions later, Karl had finished catching everyone up on what had happened, without mentioning the Holy Relic, or going into details about the attack by the Drake Riders.

Tales of foreign invasion teams would just cause tensions, and discourage missions at a crucial time for everyone's growth. The Colonel had a bit of insight into what they were up to, enough to assure her that they weren't going to attack at random all over the nation anyhow. But she didn't seem happy about all the extra work.
