Swordsmen Thralls were Thrall warriors encountered in Soul Reaver 2. As with other thrall variants, Swordsmen Thralls were undead warriors, re-animated and tasked with eternally protecting the sacred places of the Ancient vampires against intrusion, rising from underground to confront Raziel as he approached[Soul Reaver 2 manual][Soul Reaver 2 strategy guide (Prima)].[1] Visually, Swordsmen Thralls were green-skinned, heavily decaying humanoids. They wore a distinctive horned helmet, dark shoulder pads and gloves, and a short red kilt[Soul Reaver 2].
Historically, Thralls were slaves in the Viking age of Scandinavia (and the root of the word "enthrall").
Similar "Thrall" enemies, arguably inspired by the same concept would later appear in Crystal Dynamics' Tomb Raider: Underworld, where 'Thralls' were undead enemies raised by the liquid "etir". These thralls had a notably similar appearance to Legacy of Kain thralls; with the "Viking Thralls" sharing particular traits with the Swordsmen Thralls.
