I actually had a story arc back in the age-old days of ARR that may sound vaguely familiar.
A denizen from a nation under Garlean rule is fed up with the Alliance's unwillingness to commit to fighting with Garlemald. In order to force their hand and further his own personal objectives, he gathers together a force that - while dressed in the colors of the Grand Companies - assaults Garlean facilities before being stopped by a rag-tag band of heroes.
Since said character actually survived the encounter, I've played with it being that someone from his old military force that enacted his plan passed it on to a certain SLOPPEH individual who modified it for his own purposes. Said character was annoyed by the theft without credit, but also sees it as a proof of concept that his plan would have worked just fine if it wasn't for those meddling Eorzeans.
... Also he never planned to suicide himself to summon a Primal.
