Snathe

Colonel Snathe was a commanding officer on the Betrothal of Sontar, a Sontaran mining ship searching for the Worldbane. The Worldbane was believed to be the most powerful superweapon ever created and was 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)
