Snathe

Colonel Snathe was a commanding officer on the Betrothal of Sontar, a Sontaran mining ship that was searching for the Worldbane. Worldbane was believed to have been the most powerful superweapon ever created and to be located on the icy world of Serac. Snathe had the Sigil of Thanatos tattooed onto his chest to remind him of his search. (DWM: The Betrothal of Sontar)
