Of course, the boy's sudden change in plans caused a lot of problems, especially for the external forces he had called up to help deal with the situation like the Church of Artemisia and the mages of Kasteblum.
He had a bit of a hard time dealing with the political issues pertaining to the fact that his actions could potentially invite grandmaster-level existences from another Country into the Great Western Empire.
Luckily, the Emperor giving him the benefit of doubt, plus the fact that the man had spoken to the Chief Grand Magus of Kasteblum personally, made it so that the assistance force sent by Gavin did not get held up unnecessarily at the border.

He had gone through five of the Duchy's 20+ Counties and had been helping smaller towns that were affected by the 'stray' undead and could not protect themselves to evacuate to the larger cities in the Counties.
