Tiiopa'il Roonaladh I

Tiiopa'il Roonaladh I was the husband of Wensicia, daughter of usurper Audrii VIII.

He overthrew Emperor Fredhrick IX supported by House Atreides.

It seems that Siridar-Duke Telemachos Atreides intended to take the Throne and was impeached before the Landsraad and executed.
