Patch 2.7.5 created a new NPC merchant called War Research and reinstate the Enchantment Rune purchases for Alliance Points. Previously, the Akaviri Motifs and style items were sold by the siege masters vendors. Recently, Gladiator Proofs were added to the game which allow purchase special runeboxes from these vendors.
War Researcher vendor in the base camps of Cyrodiil. War Researchers sell Akaviri Motif chapters, and the Style Items for Akaviri and Alliance styles.
As more motifs are being discovered in Tamriel, it becomes harder to remember where to find all this motif lore. This guide attempts to make it easier for the new or frugal crafter to locate motif chapters without being at the mercy of motif availability on guild traders.
Motif lore can be often found home and business containers (Nightstand, Desk, Wardrobe, Dresser, Cabinet, Cupboard, Trunk / Chests, Backpacks, and Urn / Vases). Furthermore, the location of these containers often determines the types of motifs that can be found. Unfortunately, many of these containers in towns will require some caution as they are considered property of the locals and if your theft is witnessed, you will negatively affect your status with the guards.
