You know Hayden Tenno from dark sectors? He could be the stalker. He was the first Tenno after all. "Around mid-game of Dark Sector, Hayden stole a power suit/Warframe that looks simliar to the Excalibur frame" The stalker looks like Excalibur too. And it is possible that when Hayden Tenno wants to ask for help to cure his disease, people(the current tennos) mistook him for a monster and shot him down.
