Tommard Baratheon

Tommard Baratheon is one of the stillborn sons of Stannis Baratheon by his wife Selyse Florent. His mother keeps his corpse in a glass jars on display in her chamber along with his also stillborn brothers, Petyr and Edric.

Behind the scenes
Staff writer Bryan Cogman came up with the idea of the stillborn fetuses being preserved in jars. Cogman said in an interview, "It was a proud day for me as a writer when I walked on set and saw those magnificently nasty prop dead babies floating in those jars."

In the books
In the A Song of Ice and Fire book series, there is no mention Selyse Baratheon having any stillborn sons.
