Overview
br This OCW add-on re-integrates Sergius Turrianus merchant chest. It does so by re -adding the appropriate merchant factions to Sergius via SkyPatcher to avoid conflicts with NPC appearance overhauls that touch his NPC record, among other mods e.g. USSEP slapping a dead body cleanup script to his record if you murder his patronizing face .
br This gives at least another reason to keep him alive beyond being an Enchanting trainer and having to pay off Tolfdir after killing Serg
