Severean's Foreshadowing of the Mausoleum

Iata Shocker has made a coat of arms that he puts again above him in the bulkhead. Severean has gone so far as to find a mausoleum that nobody else knows about. He found one that the door was a jar that he could enter and it's got empty sarcophagus in it. And he's decided that this is his adopted family. Yeah, this is a major moment of foreshadowing and symbolism.
