Aldrich couldn't find any mention of this Skill on Conrad's record, nor he remembered it reading on the scrolls related to different Houses.
By now he had found out that besides Dungeons, there were other methods to get or transfer a few Skills genetically from one member of House to another. This was one of the reasons why nobles gave such importance to maintaining the purity of the House. And also why they abhorred children born outside the family.
Summoning Ancestral Divine Spirit and House Venomous Rose's Rose Clones were a few of such Skills. And it seemed this Trigon Dagger Formation also came under such a category. None had found out why and how these Skills popped up in a Dreamer's Record. But Aldrich thought of them as a virus, coming alive when a few lucky pureblood nobles became Dreamers.
It didn't come as a surprise that the presence of these Skills became a selection criterion among many Houses.
