Smertrios
From Jenny Everywhere Wiki
Skollops ag-Warka, a Wellsian of the 97th Cosmos, once swore “by Smertrios”. (PROSE: A Very H.G. Christmas)
Behind the scenes
In the real world, Smertrios was a Gaulish deity. After the Roman conquest, he was syncretised with Mars, the Roman God of War, hence the significance of Skollops ag-Warka, a Martian, mentioning him.
