Elara was in the forest with some adventurers. The Guild had a security force made up of one S-rank adventurer, two A-rank adventurers, and five B-rank adventurers. The group's strength was balanced and each member was able to cover another's shortcomings. The group was created with this in mind, it was only used in crises and it had been standing still for a few years.
Although the adventurers still carried out missions, they never did any more on behalf of the Guild, they were considered a wasted force because they were never really valued and were only remembered in situations like this.
The forest was devoid of any monsters, and some hypotheses were created, such as that they had fled, but that would be difficult to do without someone noticing, the moment several monsters came out of the forest, someone would surely run to the Guild to report what had happened. That's why this hypothesis was the first to be ruled out.
